✔✔Several factors distinguis the hazardous waste site environment from other
occupational situations involving construction sites with hazardous substances. Which
of the following are examples? - ✔✔Potential for an uncontrolled condition at the site
Improper control of hazardous substances can result in a severe threat to site workers
and to the general public
,the large variety and number of substances that may be present at a site
✔✔Hazard Classification - ✔✔Health Hazard- chemical
Physical Hazard- chemical
Physical safety hazards
biological hazards
ergonomic hazards
✔✔The combination of conditions on a hazardous waste site results in a working
environment that is characterized by numerous and varied hazards which: - ✔✔Answer:
none of the above
are nearly always immediately obvious or identifiable
✔✔Workers on a hazardous waste site are subject not only to the hazards of direct
exposure, but also the dangers posed by: - ✔✔the disorderly physical environment of
hazardous waste sites
the stress of working in protective clothing
✔✔What do we know about symptoms resulting from acute exposures? - ✔✔They
usually occur during or shortly after exposure
✔✔Most hazardous waste sites contain a variety of chemical substances in various
forms. Which are included? - ✔✔Gas
Liquid
Solid
✔✔Substances can enter the unprotected body by: - ✔✔Inhalation
skin absorption
ingestion
injection
✔✔What do we know about symptoms resulting from chronic exposures? - ✔✔May not
appear for several years or decades after exposure
Usually relate to low concentrations over a long period of time
✔✔Chemical exposures are generally divided into two categories - ✔✔acute and
chronic
✔✔To protect against the hazard of fire or explosion: - ✔✔Have qualified personnel field
monitor for explosive atmospheres and flammable vapors
Use non-sparking, explosion-proof equipment
✔✔Explosions and fires may arise spontaneously, but usually they result from activities
such as: - ✔✔Accidentally mixing chemicals
,Introducing and ignition source
Moving drums
✔✔There are many potential causes of explosions and fires at hazardous waste sites.
Which of the following is a good example? - ✔✔Chemical reactions that produce
explosion, fire, or heat
✔✔What do we know about oxygen? - ✔✔Oxygen is heavier than air
Oxygen is a strong oxidant which generates fire hazards
If oxygen is present there must be NO uncontrolled contact with flammables
Concentrations of 19.5% or lower are deficient
✔✔Oxygen deficiency may result from - ✔✔The displacement of oxygen by another gas
the consumption of oxygen by a chemical reaction
✔✔What is the lowest concentration of oxygen allowed? - ✔✔16%
✔✔What are the three basic ways to protect yourself from radiation? - ✔✔Reduce time
of exposure
Increase distance from exposure
Use shielding
✔✔Which radiation causes serious damage to the body? - ✔✔Gamma
✔✔Background levels of radiation are - ✔✔0.01-0.02 mrem/hr
✔✔Which radiation causes harmful burns to the skin? - ✔✔Beta
✔✔Protection for vertical drops: - ✔✔Guardrails, safety net systems, and personal fall
arrest systems
✔✔It is better to use fall prevention systems than fall protection systems because -
✔✔Prevention systems provide more positive safety means
✔✔What are the three important elements to prevent heat stress? - ✔✔Water Rest
Shade
✔✔Symptoms of heat illness - ✔✔Heat rash
fainting
heat cramps
heat exhaustion
heat stroke
✔✔Which symptom of heat illness is the most dangerous? - ✔✔Heat stroke
, ✔✔OSHA requires employers must administer hearing conservation programs at a
sound level of - ✔✔85 dBA
✔✔If employees are subjected to noise exceeding an 8 hours time weighted average
sound level of _____ dBA feasible administrative controls must be utilized - ✔✔90
✔✔What are the common effects of ergonomic injuries? - ✔✔Pain, aches, numbness,
tingling, restricted movement
✔✔What are the primary causes of musculoskeletal disorders and other ergonomic
injury? - ✔✔Excessive repetitive motions
Excessive or sustained force
Sustained or awkward body positions
✔✔What are work related ergonomic type injuries called? - ✔✔Musculoskeletal
disorders
✔✔Biohazard agents include - ✔✔Bacteria, viruses, and fungi
Rickettsia and microorganisms transmitted by fleas
✔✔Which of the following should be included in a worksite hazard plan? - ✔✔Conduct a
comprehensive, baseline survey for safety and health and periodic update surveys
Change analysis of planned and new facilities, processes, materials, and equipment
Perform routine job hazard analysis
Conduct periodic and daily safety and health inspections of the workplace
✔✔What do we know about Job Hazard Analysis (JHA)? - ✔✔It is a technique that
focuses on job tasks as a way to identify hazards before they occur.
It focuses on the relationship between the worker, the task, the tools, and the work
environment
Ideally, after hazards are identified steps will be taken to eliminate the hazard to an
acceptable risk level
JHAs are also known as Activity Hazard Analysis, Job Safety Analysis, and Task
Hazard Analysis
✔✔Four major actions form the basis from which good hazard prevention and control
can develop. What are they? - ✔✔Comprehensive surveys, change analysis, hazard
analysis, safety and health inspections
✔✔In conducting a comprehensive survey, for many activities, what would be needed? -
✔✔Survey of noise levels
Review of respirator program
Review of ergonomic risk factors
