receive ??? hours of refresher training annually. - ANSWER -8 Hours
What Part under 29 CFR regulates EMERGENCY RESPONSE to hazardous substance
releases - ANSWER -29 CFR 1910.120 ==>(Q)<==
What is the name of the standard that regulates Hepatitis B, HIV, AIDS - ANSWER -
Occupational Exposure to Bloodborne Pathogens 1910.1030
What is a hazardous substance? - ANSWER -ANY substance designated as hazardous
under ANY federal regulation.
All matter can exist in three different physical states: Solid Liquid Gas DEPENDING ON
- ANSWER -Depends on temperature and pressure
What is Specific Gravity (SG) - ANSWER -ratio of mass of substance to mass of volume
of water
SG < 1.0 will float in water
SG > 1.0 will sink in water
T or F: Aerosols are not vapors or gases, but solid or liquid particles suspended in air. -
ANSWER -True
Vapor Pressure is - ANSWER -A measure of the rate of evaporation or volatization (or
gives off vapor) from a liquid
Vapor density is - ANSWER -Vapor density equals the weight of a vapor or gas
compared to the weight of an equal volume of air at the same temperature and
pressure.
Vapor Density >1 = Heavier than air
Vapor Density <1 = Lighter than air
year the osh act was written - ANSWER -1970 under the Dept of Labor
Detailed Site-Specific Hazards Assessment must be performed according to what
federal regulation? - ANSWER -29 CFR 1910.120
, 29.CFR.1910.1200 Requires employees to - ANSWER -1.Adopt a written hazard
communication program
2.Keep SDS for chemicals on the site
3.Provide education and training to employees
T or F: Chemical Safety Data Sheets (SDS) must be prepared by every chemical
manufacturer - ANSWER -True!
New system that replaced the original HAZCOM Material Safety Data Sheet (MSDS)
System - ANSWER -GHS Global Harmonization System, simply called Chemical Safety
Data Sheets (SDS).
OSHA and EPA not interchangeable in their roles (what are their roles?) - ANSWER -
Protect human health and safeguard the environment (air, water and land).
Flash Point is - ANSWER -the minimum temperature at which a liquid fuel produces
enough vapor to burn momentarily
Fire Point is - ANSWER -The temperature at which enough vapors are given off to
support continuous burning.
Ignition (or Auto-Ignition) Temperature is - ANSWER -The minimum temperature
required to initiate or cause self-sustained combustion (burning) IN THE ABSENCE OF
ANY SOURCE OF IGNITION
Lower Explosive Limit (LEL) - ANSWER -The percentage of the minimum concentration
of vapors in the air necessary to have a fire or explosion. At 100% LEL, there are
sufficient vapors in the air for a fire or explosion
Upper Explosive Limit (UEL) - ANSWER -The maximum concentration of vapor in the
air, above which a fire or explosion will not occur in the presence of an ignition source.
Between the LEL to the UEL is the - ANSWER -Flammable Range
T or F If the time spent in a particular radiation field is doubled, the worker's dose is
doubled. and vice versa - ANSWER -True
True or False: If a PROPER shield (such as a particular filter respirator) is placed
between the radiation source and a person, the dose will be eliminated or decreased. -
ANSWER -True
PEL - ANSWER -permissible exposure limits: the max airborne concentration of a
contaminant to which an employee may be exposed over the duration specified by the
type of PEL.
