Safety Flashcards
WHMIS stands for?
Workplace hazardous materials information system
Suppliers and employers must provide?
Workplace labels
MSDS (material safety data sheet)
Education
What must be done whenever a controlled product is switched from its original container?
A workplace label must be made for the new container
WHMIS classifications see image
Class A:
Compressed gas
- explosion hazard
- take off a great speeds
- can explode if heated in fire
- explode if dropped
class B
Flammable and combustible material
Class C
Oxidizing materials
- do not usually burn themselves but they either help the fire by providing oxygen or cause materials that normally would not burn to spontaneously combust or suddenly start to burn
Class D division 1
Poisonous or infectious materials
(Causing immediate serious toxic effects)
Class D division 2
Poisonous and infectious material
Materials causing other toxic effects(chronic toxicity)
Class D division 3
Poisonous or infectious materials
(Bio hazardous infectious material)
- bacteria
- fungi
- viruses
- parasites
Are all included in this section
Class E
Corrosive material
Damage is often permanent and irreversible
Class F
Dangerously reactive materials
Key elements of WHMIS
Worker education
Product labeling
Material safety data sheet
Why is static electricity dangerous when transporting flammable liquids?
Presence is not known until spark occurs
TDGR stands for
Transporting dangerous good regulations
What is incompatibility?
When chemical reactions occur between two or more chemicals or materials
Review chart
Mechanical general ventilation is?
When air is pumped into the enclosed work area, passes through and is vented outdoors through ductwork doors or windows
Local ventilation is?
Exhaust fans that capture the fumes at their source and exhausts them outdoors
Portable smoke extractor
Air and fumes are drawn into extractor filtered and exhausted
The risk of explosion increases dramatically when you are working in containers, vessels, or confined spaces. Hazards are created by:
- Static electricity
- excessive heat and noise
- explosive, flammable, toxic, or suffocating fumes and gases
What is the only extinguishing agent for class D FIRES? (Combustible metals)
Dry powder
What is the only extinguishing agent for class K fires? (Combustible oil or grease)
Wet chemical
(Potassium acetate base)
Never fight a fire if:
- Fire could block your escape
- proper equipment to fight fire is not available
- fire has spread beyond where it has started
- the extinguisher has run out of extinguishing agent
- the extinguisher does not work
OHS means
Occupational health and safety
Three groups responsible for workplace safety?
Employer
Employee
Equipment or material suppliers
Employee and employer must work together to control hazards in what three ways?
1: use engineering controls
- using right machinery or equipment and using it right
2: use administrative tools
- safe work practices
3: use of personal protective equipment
-
Worksite specific training must cover four areas:
1: hazard information
2: different modes of product identification used in the workplace
3: procedures for safe use, storage and handling of products used at the worksite
4: procedures for dealing with fugitive emissions and emergencies at the work site
Workplace hazards fall into 4 main catagories:
1: biological hazards
2: chemical
3: ergonomically
4: physical
Engineering controls include:
- elimination
- substitution
- re-design
- isolation
- automation
If engineering controls do not eliminate or control the hazard you employer must use administrative tools which include:
- safe work practices
- work/rest schedules
- limit hours of work
- scheduling hazardous work during times when exposure of others is limited
- wet methods as opposed to dry sanding or sweeping
If engineering and administrative controls do not control the hazard what just be done?
Appropriate ppe must be supplied and used.
Five main tools for assessing and controlling work place hazards are:
1: hazard assessment reports
2: checklists
3: health and safety plans
4: emergency response plans
5 : first aid reports and incident reports
A field level risk assessment consists of:
- look around and identify hazards
- assess risks
- control risks
- resume work
Close work site is _____ Min to hospital
Distance work site is ______ min to hospital
Isolated work site is ______ min to hospital
Up to 20 min
20-40 min
More than 40min
