Close Encounters with Chemicals
 We encounter chemicals almost every day





Filling your vehicle with gasoline
Cleaning the bathroom
Applying pesticides or insecticides
Using solvents or acids at work

 Many chemicals can cause injury or illness
if not handled properly.

Hazard Communication ‘Goals’

 Right to Know chemical hazards
 PPE, first aid, spills/leaks
 Labels, Material Safety Data sheets

Right to Know
 OSHA created the Hazard Communication
Standard to help ensure your safety when
working with hazardous chemicals.
 You have a RIGHT TO KNOW about the
hazardous chemicals you use on the job and
how to work safely with those chemicals.

Hazard Communication Standard
Chemical manufacturers must:
 Determine a chemical’s hazards
 Provide labels and MSDSs
Employers must:
 Provide a hazard communication program
 Maintain MSDSs
 Train on hazardous materials

HazCom Standard (cont.)
Employees must:
 Read labels and MSDSs
 Follow employer instructions and warnings
 Identify hazards before starting a job
 Participate in training

Chemical Hazards
Physical Hazards:
 Flammable
 Explosive
 Reactive

Health Hazards:
 Corrosive
 Toxic

Routes of Entry





Skin and eye contact
Inhalation
Swallowing
Penetration (skin absorption)

Hazard Communication ‘Goals’

 Right to know and chemical hazards
 PPE, first-aid, and spills/leaks
 Labels and MSDS

Personal Protective Equipment
 Dust masks and respirators
 Glasses, goggles, and
face shields
 Hearing protection
 Gloves
 Foot protection
 Head protection
 Aprons or full-body suits

Hazardous Materials First Aid





Eyes: Flush with water for 15 minutes
Skin: Wash with soap and water
Inhalation: Move to fresh air
Swallowing: Get emergency
medical assistance

Spills and Leaks
 Evacuate the area
 Notify a supervisor or the emergency
response team
 Remove ignition sources (if safe to do so)
 Stay away

Importance of Labels
 The identity of the chemical
 Name, address, emergency
phone number of manufacturer
 Physical and health hazards
 Special handling instructions
 Basic PPE recommendations
 First aid, fire response, spill
cleanup

NFPA Labeling Systems
NFPA = National Fire Protection Association





Blue = Health
Red = Flammability
Yellow = Reactivity
White = Other hazards or special handling =
Other hazards or Special handling
Scale: 0 (No Hazard) to 4 (Extreme Hazard)

NFPA 704 System
Health Hazard

Fire Hazard

4 Deadly
3 Extreme Danger
2 Hazardous
1 Slightly Hazardous
0 Normal Material

Flash Points
4 Below 73 F
3 Below 100F
2 Above 100 F not
exceeding 200 F
1 Above 200 F
0 Will not Burn

4

4

Specific Hazard

Reactivity

ACID = acid
ALK = Alkali
COR = Corrosive
W = use no water

4 May detonate
3 Shock & heat may
Detonate
2 Violent Chemical
Change
1 Unstable, if heated

4-Severe, 3-Serious, 2, Dangerous
1-Minor, 0-None / Negligible

Other Label Warnings
 The identity of the chemical
 Name, address, emergency
phone number of manufacturer
 Physical and health hazards
 Special handling instructions
 Basic PPE recommendations
 First aid, fire response, spill
cleanup

Material Safety Data Sheets

Material Safety Data Sheets (cont.)





Personal Protective Equipment (PPE)
Safe handling and storage
Spills and leaks
Compliance issues

Hazard Communication Goals
 Right to Know and Chemical Hazards
 PPE, First aid, and Spills/leaks...
