The document outlines the hazardous materials construction safety training requirements under the haz-com standard, emphasizing employees' right to know about chemical hazards they may encounter. It details the types of chemical hazards, routes of exposure, duties of employers and manufacturers, and the importance of Material Safety Data Sheets (MSDS) for educating workers on handling hazardous materials safely. The training also includes spill response strategies and emphasizes ongoing diligence in safety practices to prevent health and environmental incidents.

1. BANYU URIP PROJECT
EPC1 - Production Processing Facilities
Contract No. C-3207067
Module 1 – Hazardous Materials
CONSTRUCTION SAFETY
TRAINING

2. Right-to-Know
 All employees have the Right-to-Know the
identity and potential hazards that are
associated with the chemicals that they work
with.

3. Hazards of Chemicals
 Physical Hazards
– Combustible Liquid
– Compressed Gas
– Flammable
– Explosive
– Oxidizer
 Health Hazards
– Toxic
– Corrosive
– Carcinogen
– Irritant
– Sensitizer
• Acute Health Hazard
– Occurs after a short period of exposure and can cause harm very
quickly.
• Chronic Health Hazard
– Occurs gradually over time.

4. Chemical Exposures
Chemicals can enter your body in one of three ways:
1. Inhalation
• Breathing hazardous chemicals could cause nausea, headaches, or
dizziness. It could also damage the lungs, throat, respiratory
system, and even cause asphyxiation or death.
2. Ingestion
• Eating or smoking after handling a hazardous chemical could cause
poisoning or damage of internal organs.
3. Absorption
• Chemicals can cause burns, rashes, allergies, and vision problems.
It’s even possible for some chemicals to pass through the skin into
the bloodstream.

5. Requirements of the Standard
 Chemical manufacturers are required to:
–Identify all physical and health hazards of any
chemical or material they produce.
–Report these hazards by:
• Attaching a warning label to each chemical
container.
• Sending an accurate MSDS to every company to
whom the chemical or material is shipped.

6. Requirements of the Standard
• The Haz-Com Standard requires each
employer that uses hazardous chemicals or
material to:
–Develop written Haz-Com Program
–List all hazardous chemicals/material on site
–Ensure MSDS available and accessible
–Provide required PPE
–Ensure thorough training

7. Warning Labels
• Warning labels are designed to alert you that a
chemical or material may be hazardous.
• The labels will include the following information:
– The identity of the chemical
– The appropriate hazard warnings
• Flammable
• Explosive
• Proper Handling & Storage
• PPE required
– The name and address of the chemical manufacturer,
importer, or other responsible party.

8. Warning Labels
• The US National Fire Protection Association (NFPA) uses the popular
diamond-shaped labels to identify the chemicals/ materials type and
severity of hazard.
– Red - Flammability
– Blue - Health Hazard
– Yellow - Reactivity Hazard
– White - Special Hazard (i.e., Do not Add Water, Corrosive, Oxidizer)
• The diamonds (except for white) will have a number in it (This scale
represents the severity of the hazard.)
– 0 - No Hazard
– 1 - Slight Hazard
– 2 - Moderate Hazard
– 3 - Serious Hazard
– 4 - Severe Hazard

9. Material Safety Data Sheets
(MSDS)
 The MSDS gives employers detailed information
about the hazards of specific chemicals and
material, as well as how to control them.
 MSDS must be made available to all employees.
 Must be posted at both storage and usage
locations
 Must be communicated to the users

10. Four Main Categories
1. Product Information
2. Exposure Situations
3. Hazard Prevention and Protection
4. Other Specific Safety Information

11. Product Information
• Basic information about the material is found in
the beginning of the MSDS
– Name of the chemical (the chemical name will be the
same as the one on the label, although other names
may also be listed
– The manufacturer’s name, address, and telephone
number
– The preparation date, or date of last revision
– Emergency telephone numbers

12. Product Information
• Specific Exposure Limits:
– Permissible exposure limit (PEL)
– Threshold limit value (TVL)
– Short-term exposure limit (STEL)
• The PEL and TVL are maximum concentrations of
the substance that you can safely be exposed to
averaged over an 8-hour workday.
• The STEL is the acceptable amount of a substance
that you can be exposed to over a fifteen minute
period.

13. Product Information
• Potential Physical and Health Hazards
– Is the material flammable, corrosive, or
toxic?
– Can the hazards enter your body and
affect your health?

14. Exposure Situations
• This section of the MSDS explains what
to do in the event of an accidental
exposure:
–First-aid measures
–Response procedures for spills or leaks
–Fire-fighting measures

15. Hazard Prevention and Protection
• The MSDS provides instruction on how to safely
handle and store materials.
• The following will allow you to:
– Minimize your contact with hazardous materials
– Reduce fire hazards
– Prevent release of hazardous materials
– Learn the conditions
• Heat
• Direct sunlight
• Vibration

16. Hazard Prevention and
Protection
• Additional Safety Issues:
– PPE
– Engineering controls
– Physical and chemical properties:
• Appearance
• Evaporation rate
• Melting and boiling points
– Stability
– Reactivity

17. Other Specific Safety
Information
• Other information on the MSDS sheet
– Toxicological
– Ecological
– Disposal
– Transportation
– Regulatory information
• Can be very beneficial and is typically utilized by specialists
– Emergency responders
– Physicians
– Toxicologists
FIRST AIDER MUST BE FAMILIAR WITH THE MSDS AND KNOW WHAT IMMEDIATE
FIRST AID IS REQUIRED

18. Usage
 MSDS at both the storage and usage areas.
 Decanted substances clearly labeled.
 Hazards and controls clearly communicated to
worker and understood.
 PPE requirements available and understood
 Emergency processes identified on the MSDS are
in place and understood.
Hazardous Materials must be included in JSA

19. 19
Hazard Communication
 Know what you are working with
 Know the risks and the precautions you must take
 If you are unsure, always ask
 Take responsibility for the safety of yourself and
your colleagues
The worker must be trained in the use of Hazardous Materials.
The hazards and controls must be communicated to the worker.

20. Summary
• The Haz-Com Standard is in place to ensure that
anyone who works around hazardous chemicals or
material:
– Understands their specific hazards
– Has the information, knowledge, and personal
protective equipment to be proactive in the prevention
of safety & health incidents

21. Spill Category
Minor Spill (to be recorded):
• Spill on to land :
- Material < 150 L (1 barrel)
- Chemical < 100 kg
Major Spill (to be recorded and reported):
• Spill on to land :
- Material > 150 L (1 barrel)
- Chemical > 100 kg
• Spills of Materials into Water Bodies (any
quantity)

22. SPILL PREVENTION STRATEGIES
Activities / Areas Strategy
Storage and Disposal All areas where hazardous wastes, diesel fuel, vehicle fluids, and other liquid materials
that pose a potential threat to human health and/ or the environment (e.g., solvents,
acidic/ caustic solutions, herbicides/ pesticides) are stored and dispensed will be
inspected on a minimum weekly basis by Environmental Engineer in order to identify
drips, small leakages, and situations that could give rise to a spill.
Hazardous wastes will be stored in sealed drums or other suitable sealed
containers placed in hazardous waste collection facilities/ areas at TS site.
Hazardous waste collection facilities/areas will possess secondary containment
capabilities
Liquid materials that pose a potential threat to human health and/ or the environment
will be stored in sealed containers or small tanks placed within designated areas/
facilities that possess secondary containment capabilities or within temporary earthen
beamed areas underlain by an impervious liner.
Diesel fuel will be stored at TS maintenance facility in aboveground storage tanks
placed within a lined containment pad.
Material Transportation Liquid hazardous wastes and material will be transported in a manner that provides
the waste with secondary containment (i.e., via the use of Over Packs or other similar
devices).

23. SPILL RESPONSE EQUIPMENT
Spill onto land :
• Sand sacks
• Sand,
• Shovel
• Sorbent pad
• Thick plastic bags, drums and/or Over Packs
for the recovery and storage of contaminated
