Respiratory protection devices are available in two basic design types: Air-Purifying Respirators (APR) and Supplied-Air Respirators (SAR). As a trained hazardous materials specialist, your employer asks you to evaluate each of the following four possible workplace conditions:

1.       Fiberglass components are being sanded smooth prior to painting by assembly line workers.

2.       A leak in a nitrogen supply line within a service closet requires repair but the supply of nitrogen cannot be interrupted.

3.       Hydrochloric acid vapor is escaping from a cylinder stored in an outdoor area. Oxygen levels are measured and found to be above 19.5%.

4.       A full 55-gallon drum of an organic solvent commonly used in the production process is releasing vapor.

For each of the above four conditions:

• Select the preferred type of respiratory protection device.

• Identify which standardized OSHA filter color the device should be fitted with (if not applicable, so state).

• Explain your rationale for choosing the device type.
