10. Any alteration of the physical, chemical, and biological properties of the atmospheric air.
A. air pollution C. pollution
B. atmospheric pollution D. water pollution

The concentration in air that should not be exceeded during any part of the working exposure. Ceiling limits may supplement other limits or stand alone. Developed by the American Conference of Governmental Industrial Hygienists (ACGIH).

2. D.Risk assessment is a term used to describe the overall process or method where you:

Identify hazards and risk factors that have the potential to cause harm (hazard identification).

Analyze and evaluate the risk associated with that hazard (risk analysis, and risk evaluation).

3. B. Occupational safety and health (OSH) is a cross-disciplinary area concerned with protecting the safety, health and welfare of people engaged in work or employment. The goals of occupational safety and health programs include to foster a safe and healthy work environment.

4. B. A lower flash point indicates higher flammability. Measuring a flash point (open-cup or close-cup) requires an ignition source. At the flash point, the vapor may cease to burn when the ignition source is removed.

5.D.Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials. Operations strategy can be viewed as part of a planning process that coordinates operational goals with those of the larger organization.

6.The short-term exposure limit (STEL) is the time-weighted average concentration of a substance over a 15 min period thought not to be injurious to health. The HSE Publication EH40 gives exposure limits for a wide range of chemicals (see “Further Reading”).

7.C The threshold limit value ceiling of a chemical is the concentration that

Threshold Limit Value – Ceiling (TLV-C): the concentration that should not be exceeded during any part of the working exposure.

8 .B.Fire is one type of hazard that needs careful evaluation before extinguishing it. Not all fire could be extinguished by water that is why it is necessary that we knew first the cause of fire before dealing the fire.

9. B. Fire

10 A. Air Pollution - Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution.
