SAFE CHEMICALS, SAFE PROCESSES SDS/MSDS Handling • Hazard Communication • Solvent Safety • Emergency Preparedness • OCP Development
Core philosophy
“An SDS sitting in a computer is information. An SDS converted into a safe work practice is control.”
This workshop would move participants through:
Chemical → Hazard → Exposure → Risk → Control → Emergency → Standard Work → Verification
MSDS
= Material Safety Data Sheet
SDS
= Safety Data Sheet
What’s the difference?

Frequently used abbreviations:
SDS (formerly MSDS) – Safety Data Sheet
“MSDS is the old name. SDS is the current standard—but
the purpose remains the same: to tell us what the chemical is, what hazards it
presents, how to handle and store it safely, what PPE is required, and what to
do in an emergency.”
The Chemical Abstracts Service (CAS) is a division of the
American Chemical Society (ACS) that provides the world's largest and most
comprehensive collection of publicly disclosed chemical and scientific research
data
LEV - Local Exhaust Ventilation - An LEV system is an engineering control designed to capture and remove harmful airborne contaminants (such as toxic vapors, chemical fumes, and dust) directly at or near the source before they can spread into the workplace or be inhaled by workers.
DAY 1 — SDS, CHEMICAL HAZARDS & SOLVENT SAFETY
Activity: “What chemical do you work with?”
Give every participant a card:
Name one chemical/solvent that you personally encounter
at work.
Then ask:
What
is it?
Why
is it used?
What
is its main hazard?
What
PPE do you use?
What
would you do if it spills?
Where
is its SDS?
When
was the SDS last reviewed?
Most participants will discover that they know the chemical
name, but not necessarily the control requirements.
Takeaway
“If I cannot explain the chemical's hazard, exposure
route and emergency action, I am not yet controlling the chemical.”

THE SDS SAYS…
SECTION 1 — IDENTIFICATION
Product: Paint Thinner Product type: Solvent / thinner for paints and coatings Form: Liquid Use: Paint thinning / cleaning, depending on product specification
Critical lesson
“Thinner” is not sufficient chemical identification.
Participants should ask:
Which thinner? Which manufacturer? Which product code?
Which SDS revision?
SECTION 2 — HAZARD IDENTIFICATION
A representative paint-thinner SDS identifies hazards
including flammability, skin/eye irritation and health effects associated
with vapour exposure. Some formulations may have additional chronic-health
classifications depending on their ingredients.
Typical hazard themes
🔥Flammable
liquid/vapour
⚠️Skin/eye irritation
🫁
Harmful effects from vapour exposure
🧠Possible
nervous-system effects depending on formulation/exposure
🌱Potential
environmental hazard depending on composition
Signal word
May be:
DANGER
or
WARNING
depending on the specific product classification.
Trainer question
Ask:
“Did anyone say that the main risk was simply ‘chemical
contact’?”
A representative published paint-thinner SDS lists a mixture
containing petroleum distillates/Stoddard solvent and smaller quantities of
components including mixed xylenes, trimethylbenzene, nonane, ethylbenzene and
naphthalene.
Example training representation
Component category
Why it matters
Petroleum distillates
Flammability / aspiration concerns
Aromatic solvents such as xylene
Vapour exposure
Ethylbenzene
Health hazard considerations
Other hydrocarbons
Fire/exposure/environmental concerns
BIG LEARNING MOMENT
Ask:
“When the container says PAINT THINNER, does that mean it
is one chemical?”
Answer:
No.
It can be a mixture of several chemicals.
Therefore:
Never assume the hazard profile of one thinner applies to
another thinner.
Move the affected person away from exposure into fresh air
and seek medical attention when symptoms or significant exposure warrant it. A
representative SDS advises medical consultation following significant exposure.
Skin
Remove contaminated clothing and wash/rinse the affected
area thoroughly.
Eyes
Immediately flush with plenty of water and continue rinsing;
remove contact lenses if easy to do so. Seek medical attention if irritation
persists or as specified by the actual SDS.
Ingestion
Do NOT induce vomiting.
Seek medical attention.
This is an excellent opportunity to ask:
“What is the first thing you should NOT do after
ingestion?”
SECTION 5 — FIREFIGHTING
Representative SDS information identifies suitable media
such as:
Alcohol-resistant
foam
CO₂
Dry
chemical
and warns against inappropriate high-volume water jets for
the product. (Scribd)
Important emergency hazards
Participants should identify:
🔥 Vapour can ignite.
🔥 Fire can spread
rapidly.
🔥 Containers exposed to
fire can become hazardous.
🔥 Firewater/runoff can
create environmental contamination.
FACILITATOR QUESTION
Ask:
“If 5 litres of thinner spills, should we immediately
start cleaning it?”
Correct response:
NO — first assess the situation.
First:
Isolate → eliminate ignition sources → assess exposure →
use appropriate PPE → control the spill if trained and safe to do so.
SECTION 6 — ACCIDENTAL RELEASE
Representative SDS guidance includes:
Personal precautions
Keep
unnecessary people away.
Increase
ventilation where safe.
Eliminate
ignition sources.
Use
appropriate PPE.
Approach
from upwind where applicable.
Environmental precautions
Prevent entry into:
Drains
Sewers
Watercourses
Basements/confined
areas
Spill control
Use appropriate non-combustible absorbent such as:
Sand
Earth
Vermiculite
Diatomaceous
earth
and collect contaminated material for appropriate disposal.
(afdpetroleum.com)
THE TRAINER'S TRAP
Ask:
“Where should you stand while dealing with a solvent
spill?”
Participants may say:
“Near the spill so I can clean it.”
Correct thinking:
Consider wind direction and vapour movement.
Don't put yourself in the vapour path.
SECTION 7 — HANDLING & STORAGE
This is one of the most important sections for your
automotive audience.
Representative SDS guidance includes:
Keep away from:
🔥 Open flames
🔥 Sparks
🔥 Hot surfaces
🔥 Smoking
🔥 Other ignition sources
Control static electricity
The SDS specifically warns that static discharge can ignite
organic vapours. (Scribd)
Handling
Avoid
breathing vapours.
Avoid
unnecessary skin/eye contact.
Provide
adequate ventilation.
Keep
containers closed.
Avoid
aerosol generation.
Take
precautions against static discharge.
Storage
Keep
containers tightly closed.
Store
in a cool, dry, well-ventilated location.
Keep
away from ignition sources.
Keep
containers upright.
Follow
the product's storage compatibility requirements. (Scribd)
PARTICIPANTS TO PONDER
Question 1
“Can I keep an open thinner container beside a welding
station?”
NO.
Question 2
“Can I leave the container open because I am using it
continuously?”
Not simply because it is convenient. Follow the actual
SDS/OCP and use an appropriate closed/controlled system.
Question 3
“Can I transfer thinner into an ordinary plastic bottle?”
Not unless the container is approved/compatible and the
workplace procedure specifically permits it.
The SDS may tell you what PPE is appropriate, but the
workplace must first consider:
Engineering controls
Local
exhaust ventilation
Closed
transfer
Enclosed
cleaning
Vapour
capture
Appropriate
ventilation
Administrative controls
Safe
work procedure
Restricted
access
Exposure
time
Training
Chemical
handling authorization
PPE
Selected according to:
Chemical
Concentration
Duration
Task
Exposure
route
Manufacturer
compatibility information
A representative SDS calls for appropriate eye protection
and impervious protective clothing and advises that glove suitability should be
discussed with the glove manufacturer/supplier. (Scribd)
CRITICAL TRAINER QUESTION
Ask:
“Is an N95/dust mask the same as protection against
solvent vapour?”
Answer:
No.
A particulate mask is not automatically an appropriate
control for organic solvent vapours.
Respiratory protection, where required, must be selected
based on the actual chemical, exposure assessment, concentration, workplace
conditions and applicable respiratory-protection programme.
SECTION 9 — PHYSICAL & CHEMICAL PROPERTIES
This section is where the participants should discover why
the solvent is dangerous.
A representative paint thinner SDS reports approximately:
Appearance
Liquid
Boiling range
Approximately 158–198°C
Flash point
Approximately 39–45°C
Water solubility
Negligible
Relative density
Approximately 0.775–0.784
Auto-ignition temperature
Approximately 276°C
These values are product-specific and should be replaced
with the actual customer's SDS values during training. (Scribd)
NOW ASK THE PARTICIPANTS
Question 1
“If the flash point is around 40°C, what happens in a hot
Indian shop floor?”
They should start thinking:
Temperature → vapour generation → ignition potential
Question 2
“Does the absence of visible smoke mean the solvent is
safe?”
NO.
Vapour can be present even when there is no visible cloud.
Question 3
“Can you smell the chemical and use smell as your
exposure control?”
NO.
Odour is not a reliable substitute for exposure assessment
or ventilation control.
SECTION 10 — STABILITY & REACTIVITY
A representative paint-thinner SDS identifies
incompatibilities such as oxidizing agents and certain strong
acids/bases/halogens depending on formulation. (Scribd)
Participants should learn to look for:
Incompatible materials
Conditions to avoid
Hazardous decomposition products
Possibility of hazardous reactions
ACTIVITY: “WHERE SHOULD THIS GO?”
Give participants:
Chemical A
Paint thinner
Chemical B
Strong oxidizer
Chemical C
Strong acid
Chemical D
Water
Ask:
“Can these all be stored together?”
Participants must refer to Section 7 + Section 10,
rather than guessing.
SECTION 11 — TOXICOLOGICAL INFORMATION
This section tells participants about potential health
effects.
Depending on the formulation, solvent exposure may involve:
Skin
irritation
Eye
irritation
Respiratory
irritation
Headache
Dizziness
CNS
effects
Effects
from repeated/prolonged exposure
Aspiration
hazards for certain hydrocarbon mixtures
Some paint-thinner SDSs specifically warn about dizziness
and longer-term organ effects depending on formulation. (NextSDS)
ROLE PLAY
One participant plays:
Worker
“I feel dizzy, but I can finish the job.”
Another plays:
Supervisor
What should the supervisor do?
The objective is to reinforce:
Symptoms are not a production-delay problem. They are a
potential exposure warning.
SECTION 12 — ECOLOGICAL INFORMATION
Participants should consider:
Aquatic
toxicity
Persistence
Bioaccumulation
where applicable
Environmental
release
Ask:
“Why shouldn't solvent go into the floor drain?”
Because:
Production area → Drain → Sewer/ETP/water environment
can become an uncontrolled chemical release.
SECTION 13 — DISPOSAL
Discuss:
Used solvent
Contaminated absorbent
Contaminated PPE
Empty chemical containers
Paint/solvent waste
Participants should determine:
Who collects it?
Where is it stored?
What container?
How is it labelled?
Who is authorized to dispose of it?
SECTION 14 — TRANSPORT
Ask:
“Can we simply carry a 20-L solvent container across the
plant?”
Participants must consider:
Container
integrity
Closure
Labelling
Approved
trolley/handling method
Spill
protection
Internal
transport route
Ignition
sources
Quantity
Emergency
preparedness
SECTION 15 — REGULATORY INFORMATION
This section should be treated as supporting information,
not as a substitute for the company's legal register.
Ask:
“Does the SDS alone tell us whether our process is legally
compliant?”
Answer:
No.
The plant must evaluate applicable:
Indian
legal requirements
State
requirements
Factory
requirements
Environmental
requirements
Fire
requirements
Company
standards
Customer/OEM
requirements
SECTION 16 — OTHER INFORMATION
This is where participants should look for:
SDS
revision date
Previous
revision
Preparation
date
Abbreviations
Sources
Classification
methodology
Additional
information
Critical question
“What if your department has an SDS from 2018 while the
supplier has issued a revised SDS?”
That becomes a:
SDS MANAGEMENT / MOC ISSUE
MOC = Management of Change
In an automobile manufacturing plant, MOC is a formal
process used to evaluate and control risks before making a change that
could affect safety, quality, environment, production, or compliance.
In your chemical-safety training, MOC is especially
important.
A change could be:
Introducing
a new chemical/solvent
Changing
the chemical supplier
Changing
the chemical formulation
Increasing
the quantity stored
Changing
the storage location
Changing
the dispensing/transfer method
Replacing
manual cleaning with an automated process
Changing
ventilation/LEV
Introducing
new equipment
Changing
the process temperature/pressure
Changing
an OCP or work method
Using
a chemical for a new application
Example — Paint Thinner
Suppose the plant currently uses:
Thinner A
Procurement proposes:
Thinner B — cheaper and faster-drying
It should not simply be purchased and introduced.
The MOC process asks:
MOC Question
What to check
What changed?
Chemical formulation/supplier
Is the new chemical safer?
Compare SDS
What are the hazards?
Flammability, toxicity, exposure
Is the flash point different?
Compare SDS Section 9
Are incompatible materials different?
Section 10
Is existing PPE suitable?
Section 8
Is ventilation adequate?
Exposure/control assessment
Can it be stored with existing
chemicals?
Sections 7 & 10
Does the emergency response change?
Sections 4–6
Does the OCP need revision?
Yes/no
Do workers need retraining?
Yes/no
Does waste handling change?
Section 13
Are legal/company requirements
affected?
Compliance review
Who approves the change?
Defined MOC authority
The key principle
No significant change should be introduced until its
risks have been evaluated and the necessary controls are in place.
“The new solvent is 18% cheaper, cleans faster and
production wants to introduce it tomorrow.”
Then give them:
Old
solvent SDS
New
solvent SDS
Existing
OCP
PPE
specification
Chemical-store
layout
Emergency
response card
Ask:
“Can production start using the new solvent tomorrow?”
Teams must conduct a mini-MOC and decide:
🟢APPROVE
🟡APPROVE WITH
CONDITIONS
🔴DO NOT APPROVE
This is an excellent way of teaching MOC because
participants experience that MOC isn't paperwork—it is a decision-making
barrier against introducing uncontrolled risk.
THE BIG REVEAL
Now put these two columns on the screen:
WHAT I THOUGHT
Participant assumption
Reality
“Thinner is just paint solvent.”
It can contain multiple hazardous
components.
“The main hazard is skin contact.”
Fire/vapour exposure can be major
hazards.
“Gloves make it safe.”
Controls must follow the hierarchy of
controls.
“If I can't see vapour, there is no
vapour.”
Vapour can be present without visible
indication.
“Smell tells me if exposure is
dangerous.”
Odour is not an exposure-control
method.
“I can use it near welding if
careful.”
Ignition-source control is critical.
“All thinners are the same.”
Formulations and hazards vary by
product.
“The SDS is an EHS document.”
SDS information must become
operational controls.
“Spill = start cleaning.”
First assess, isolate and control
ignition/exposure.
“PPE is the solution.”
PPE is one part of a hierarchy of
controls.
THE FINAL “ARE YOU SURE?” ROUND
Now present these 10 statements.
Participants hold up:
🟢 SAFE
🔴 STOP
🟡 VERIFY
1.“The thinner container is labelled, so we can use it.”
VERIFY
Label alone isn't enough. Check SDS, task and controls.
2.“The SDS says flammable, so keep it away from ignition
sources.”
SAFE
Correct, but determine what ignition-source controls are
required.
3.“Wear gloves and start cleaning.”
STOP
Assess spill, ignition, vapour, PPE and response
requirements first.
4.“There is welding 8 metres away.”
STOP
Evaluate the ignition risk and hot-work controls.
5.“The worker smells solvent.”
STOP / VERIFY
Investigate ventilation/exposure rather than treating smell
as a normal operating condition.
6.“The ventilation system isn't working, but the job is
urgent.”
STOP
Do not allow production urgency to override critical
controls.
7.“The thinner is in a drinking-water bottle because it
is only temporary.”
STOP
Unacceptable chemical identification/control practice.
8.“The SDS is available in the EHS office.”
VERIFY
Critical SDS information needs to be accessible to those who
need it where the work is performed, consistent with the company's system.
9.“The operator has been doing this job for five years.”
STOP
Experience does not eliminate chemical hazards.
10.“We have PPE, therefore the chemical is controlled.”
STOP
Ask:
What is the higher-level control?
THE FINAL LEARNING MOMENT
Show this equation:
SDS ≠ OCP
Instead:

Participant Takeaway Card
I would give each participant this small card after the
activity:
BEFORE USING A CHEMICAL
1 — IDENTIFY - What exactly is it?
2 — CHECK SDS - What can it do?
3 — ASSESS - How can I be exposed?
4 — CONTROL - Can I eliminate/substitute/enclose/control
it?
5 — PROTECT - What PPE is actually required?
6 — PREPARE - What if it spills, burns or exposes
someone?
7 — VERIFY - Are the controls actually working?

MODULE 2 — SDS/MSDS Masterclass
10:00–11:15
India's regulatory framework specifically provides for
Safety Data Sheets under the Manufacture, Storage and Import of Hazardous
Chemical Rules. The Schedule 9 SDS format includes chemical identity,
physical/chemical data and other safety information. (India Code)
BIS material also describes the SDS/MSDS as a core element
of hazard communication and identifies the familiar 16-section format. (BIS)

MODULE 4 — Solvent Safety
This should be one of the strongest modules because solvent
exposure is highly relevant to automotive painting and maintenance.
Research in automotive painting has demonstrated
occupational exposure to volatile organic solvents, including toluene, xylene,
ethylbenzene and n-butanol, and highlighted the need to improve exposure
controls. (ScienceDirect)
A 2023 study involving 115 workers in an automobile
manufacturing factory reported elevated exposure-related risks for several
vapours/fumes, including benzene, toluene, xylene and 2-butoxyethanol.
A 2026 study specifically examining workers in an
automobile-industry paint unit reported benzene exposure above the applicable
occupational exposure limit in the studied setting.

Hands-on Activity 2 — Solvent Risk Challenge
Scenario:
A maintenance technician is cleaning an equipment component
using a solvent in a partially enclosed area. The solvent is transferred from a
20-L container into a small open tray. An exhaust fan is running
intermittently. A welding activity is taking place approximately 8 metres away.
Ask:
Team 1 — Identify hazards
Team 2 — Identify possible consequences
Team 3 — Identify missing controls
Team 4 — Rewrite the procedure safely
https://youtu.be/jEkHiP_xqUA?si=3K6Q8KcGT4plX8j8
MODULE 5 — Hierarchy of Controls
14:30–15:15
Teach:
Eliminate

PPE
Then give this challenge:
“Do not solve every problem with gloves.”
Example
Problem:
Solvent vapour during cleaning
Weak solution:
Wear respirator.
Better:
Substitute solvent.
Better:
Enclosed cleaning system.
Better:
Local exhaust ventilation.
Then:
Work instruction + exposure monitoring.
Finally:
Appropriate PPE.
Activity 3 — “Control Ladder”
Each team receives five control cards and must arrange them
from strongest to weakest.
Then participants identify where their own workplace
currently sits.
Takeaway
PPE is the last line of defence, not the first line of
design.
India has dedicated Chemical Accidents (Emergency
Planning, Preparedness and Response) Rules, 1996, covering preparedness and
response to chemical accidents. (Wildlife
Institute of India)
The current Occupational Safety, Health and Working
Conditions Code, 2020 is recorded by India Code as enforced from 21 November
2025 and includes provisions dealing with hazardous processes, emergency
standards, chemical exposure limits and worker rights concerning imminent
danger.
☐ Close container ☐ Clean equipment ☐ Dispose waste correctly ☐ Inspect area ☐ Return chemical to designated location ☐ Report abnormalities
MODULE 9 — Real-World Case Studies
Case Study 1 — Chennai thinner fire
In February 2025, a chemical factory in Thirumullaivoyal,
Chennai, caught fire after a thinner leak during loading. The chemical
ignited and the fire spread rapidly through the warehouse; a nearby school was
evacuated because smoke reached the premises. (The
Times of India)
Training question
If this happened in your plant, what would your SDS/OCP
have required before loading began?
Teams investigate:
Container
integrity
Transfer
procedure
Static/ignition
control
Ventilation
Spill
response
Loading-area
segregation
Emergency
notification
Nearby-vulnerable-population
considerations
Lesson
Chemical handling risk extends beyond the operator.
Case Study 2 — Solvent fire, Bhopal, 2025
In March 2025, a fire at an industrial-solvent manufacturing
factory in Bhopal involved around 40,000 litres of chemical petroleum
product. The fire reportedly began in an area where chemical product was
being refilled into smaller containers. Firefighters used foam and required
multiple agencies to control the incident. (The
Times of India)
Exercise
Give participants:
“Design the safe refilling OCP.”
They must identify:
Bonding/grounding
Ignition
control
Ventilation
Container
compatibility
Transfer
equipment
Quantity
controls
Spill
containment
Firefighting
medium
Emergency
isolation
Case Study 3 — Solvent storage + welding
In October 2025, a chemical manufacturing unit in Solapur
experienced a major fire after welding sparks contacted a solvent container.
The fire spread through chemical containers stored around the facility. (The
Times of India)
Question
“What failed: SDS, JSA, PTW, storage, housekeeping or
supervision?”
The correct answer is deliberately not one item.
Participants construct the barrier failure chain:
Welding
→
Ignition source
→
Solvent
→
Poor segregation
→
Fire spread
→
Emergency response
This is an excellent bridge between chemical safety +
permit-to-work + OCP.
Case Study 4 — Ahmedabad solvent tank explosion, 2026
In June 2026, an explosion at a chemical manufacturing
facility in Ahmedabad involved a tank containing a chemical solvent. One person
died and three were injured; investigators were examining the cause and
potential safety violations/operational lapses. (The

Case Study 5 — Alipur paint factory fire
The 2024 Alipur paint-factory disaster in Delhi killed 11
workers. Reporting indicated that the facility was involved in paint
manufacturing/packaging and that welding work was being conducted around the
operation. (The
Indian Express)
A subsequent police chargesheet reported that the owners
were allegedly aware that the premises were vulnerable to fire. (The
Indian Express)
Exercise
“What should have stopped the accident?”
Teams identify:
Unsafe
premises
Hot
work
Chemical
storage
Ignition
sources
Emergency
exits
Fire
protection
Worker
awareness
Supervision
Permit-to-work
Management
responsibility
Key lesson
A procedure is worthless if the workplace design makes
the procedure impossible to follow.
Case Study 6 — Automotive VOC exposure
A 2023 study of an automobile manufacturing factory found
significant exposure-related risks associated with multiple vapours and fumes,
including benzene, toluene, ethylbenzene, xylene and 2-butoxyethanol. (ScienceDirect)
Activity
Give participants:
Chemical → Exposure → Control
They must build the hierarchy:
Exposure
Possible control
Open solvent cleaning
Closed cleaning
Manual pouring
Closed transfer
Paint vapour
LEV
Solvent storage
Closed cabinet
VOC accumulation
Ventilation
Skin exposure
Engineering + gloves
Waste solvent
Closed waste container
Module 10 — Emergency Drill Design
10:00–11:00
Scenario
“Paint thinner spill during production.”
Give participants:
Plant
map
SDS
Emergency
contacts
PPE
cards
Spill
kit inventory
Fire
extinguisher options
Then announce:
“5 litres of thinner has spilled near the production
line.”
After 3 minutes:
“One worker reports dizziness.”
After 5 minutes:
“An ignition source is discovered nearby.”
After 8 minutes:
“The spill has reached a drain.”
Teams must dynamically respond.
This is much more engaging than a lecture.
Module 11 — Chemical Safety Audit
11:15–12:15
Conduct a simulated shop-floor audit.
Chemical Safety Audit Checklist
Identification
☐ Chemical identified ☐ Container labelled ☐ SDS available ☐ SDS current ☐ Workers know location of SDS
I strongly recommend giving every participant a laminated
version.
BEFORE USING ANY CHEMICAL
STOP
S — See the label
T — Think about the hazard
O — Obtain/read SDS
P — Protect yourself
Then:
CHECK
Chemical
SDS
PPE
Ventilation
Ignition sources
Spill kit

5. Five Golden Rules for the Shop Floor
I would put these on the final training slide and posters.
1.No label = No use
2.No SDS = Stop and verify
3.Unknown chemical = Do not handle
4.Spill = Control the area before controlling the spill
5.New chemical = Management of Change
6. Movies / Indian Cinema to Make the Training Memorable
1. The Railway Men
This is the best fit.
The series dramatizes the 1984 Bhopal disaster and follows
railway workers responding to the toxic gas leak. Netflix describes the story
as involving a deadly gas leak and the railway workers' emergency response. (Netflix)
Use it for:
Emergency preparedness
Communication failure
Decision-making under pressure
Incident response
Human factors
Suggested clip discussion
Ask:
“What information did people need but not have?”
“Where did communication fail?”
“What should an emergency information card contain?”
2. Bhopal: A Prayer for Rain
Use selected scenes to discuss:
Chemical
hazard
Process
safety
Management
responsibility
Warning
signs
Emergency
preparedness
Safety
culture
Important: present the movie as a discussion trigger,
not as the authoritative factual source.
3. Bhopal Express
Another option for discussing the human impact of a chemical
disaster.
4. Kaala / Factory & worker-context scenes
Can be used more broadly to initiate discussion around:
Worker
conditions
Management
decisions
Community
impact
Organizational
responsibility
Not a direct SDS training film, but useful for the safety
culture discussion.
7. News Articles as Training Triggers
Instead of using old accident stories exclusively, use recent
Indian industrial incidents.
Chennai — February 2025
Thinner leak during loading → fire → nearby school
evacuation. (The
Times of India)
Question:
“What would your loading OCP have prevented?”
Bhopal — March 2025
Approximately 40,000 litres of chemical petroleum product
involved in a major solvent-factory fire. (The
Times of India)
Question:
“Is your chemical inventory based on containers or actual chemical quantities?”
Ahmedabad — June 2026
Chemical solvent tank explosion → fatality and injuries. (The
Times of India)
Question:
“What barriers should exist before chemical transfer/reaction operations?”
Solapur — October 2025
Welding sparks contacted a solvent container and triggered a
major fire. (The
Times of India)
Question:
“Where did the hot-work control system fail?”
Alipur — 2024
Paint factory fire killed 11 workers; subsequent
investigation raised issues concerning known fire vulnerability. (The
Indian Express)
Question:
“What happens when management knows about a risk but the risk remains?”
8. Research Papers for the Training
These can become a “Research Corner” in your
participant workbook.
1. Automotive manufacturing vapours/fumes
Health risk assessment of exposure to various vapors and
fumes in a factory of automobile manufacturing
Heliyon, 2023.
Very relevant because it examined workers in an automobile
manufacturing environment and assessed exposure-related health risks from
multiple vapours and fumes. (ScienceDirect)
2. Automotive paint-shop BTEX exposure
Study of exposure to benzene, toluene, ethylbenzene, and
xylenes (BTEX) and protective effects of Gallic acid on oxidative stress on
peripheral lymphocytes of workers in the paint unit of an automobile industry
Toxicology Reports, 2026.
Especially useful for your paint-shop module, because
the research specifically examined an automobile-industry paint unit and worker
exposure. (ScienceDirect)
3. Automotive-sector solvent exposure
Controlling Painters' Exposure to Volatile Organic
Solvents in the Automotive Sector of Southern Colombia
Safety and Health at Work, 2019.
Useful for explaining why engineering and administrative
controls matter even when exposure does not necessarily exceed every regulatory
limit. (ScienceDirect)
4. Automotive paint-worker carcinogen exposure
Exposure Assessment Suggests Exposure to Lung Cancer
Carcinogens in a Painter Working in an Automobile Bumper Shop
Safety and Health at Work, 2013.
This case study examined exposure during spray painting,
sanding and heat treatment and reported elevated airborne hexavalent chromium
during one spray-painting activity. (ScienceDirect)
5. Paint/coatings VOC risk
Volatile organic compound emissions and health risk
assessment in paint and coatings industry
Environmental Pollution, 2021.
Useful for discussing VOC emissions, solvent selection and
risk reduction. (ScienceDirect)
9. Indian Regulatory Reference Pack
The participant workbook should include a “Know Your
Legal/Reference Framework” page.
Key references
Manufacture, Storage and Import of Hazardous Chemical
Rules, 1989
The Indian framework includes a prescribed SDS format and
requirements relating to hazardous chemicals. (India Code)
Chemical Accidents Rules, 1996
The Chemical Accidents (Emergency Planning, Preparedness
and Response) Rules, 1996 address preparedness and response to chemical
accidents. (Wildlife
Institute of India)
OSHWC Code, 2020
India Code currently records the Occupational Safety,
Health and Working Conditions Code, 2020 with an enforcement date of 21
November 2025 and provisions covering hazardous processes, emergency standards,
exposure limits and imminent danger. (India
Code)
ISO 45001
ISO 45001 provides the OH&S management-system framework
covering hazard identification, risk assessment, operational controls,
emergency preparedness, incident investigation and continual improvement. The
2018 edition remains listed by ISO as current, while a second edition is being
developed. (ISO)
Important: For an actual OEM implementation, the
legal register should be validated against the applicable state rules,
factory licence conditions, chemical quantities, processes, environmental
approvals and the company's internal EHS standards. This training should
not be treated as legal advice.

12. The strongest closing exercise
End Day 2 with this question:
“If you return to your workplace tomorrow and change only
ONE thing because of this training, what will it be?”
Each participant writes:
MY ONE CHANGE
I will change: __________
Because: __________
By: __________
Owner: __________
Evidence: __________
Then participants pair up and challenge each other:
“How will you prove that it actually happened?”
That converts training into accountability.
Recommended training philosophy
For this particular automobile manufacturing audience, I
would position the programme as:
“SDS is not a document to keep in a file. It is an
operational control input.”
And the complete chain should be visually reinforced
throughout both days:
