Personal Protective Equipment Types
| Question | Answer |
|---|---|
| What is PPE? | Personal Protective Equipment |
| Agencies that require PPE are: | OSHA 29 CFR 1910 and reinforced by EPA 40 CFR 400 |
| What is the purpose of PPE? | To protect the wearer from safety and health hazards, and to prevent injury from incorrect use or malfuntion of equipment |
| What is SCBA? | Self-contained breathing apparatus. Air supply comes from a source carried by the user. |
| What is SAR? | Supplied-air respirators. Air source is at a distance and user is connected through an air-line hose. |
| What is the usage time for a SCBA respirator? | Average use is 30 minutes |
| What are the uses for a SCBA respirators? | 1 For escape only and 2) Both entry and escape from hazardous atmosphere |
| What is a escape only SCBA? | SCBA with continuous flow devices with hoods that can be donned |
| There are 2 types of Entry-and-Escape SCBA, what are they? | Open-circuit (air is exhaled into ambient atmosphere), and Closed-circuit (air is recycled by removing carbon dioxide with alkaline scrubber) |
| Positive-Pressure respirators | Maintain positive pressure in facepiece druing both inhalation and exhalation. Positive pressure respirators are recommended for work at hazardous waste sites. |
| Negative-Pressure respirators | Draw air into the facepiece through the negative pressure created by inhalation. DISADVANTAGE is that if a leak develops the user can breathe contaminated air into the facepiece during inhalation. |
| Air purifying devices (3 types) | 1) Particulate filters, 2) cartridges and canister (for specific gases and vapors), and 3) combination devices (cartridges usually attach directly to the respirator facepiece) |
| Level A | Offers highest level of protection both for respiratory and dermal protection when working with EH materials. When working with unknown substances would need: SCBA, fully encapsulated suit with dual protection gloves and boots and two-way communications. |
| Level B | Little/no splash hazard, poor ventilation, low oxygen. Need pressure demand SCBA, chem resistant suit, gloves, boot covers, 2-way communication. |
| Level C | lower level respiratory/dermal protection. Used for working with known airborne contaminants. Would use Air Purifying Respirator (APR) w/ boots, escape mask, 2-way communication. |
| Level D | Little/no respiratory/dermal protection. Used when working in known low level contaminants. Chemical resistant coverall clothing, work gloves, steel toed boots and chemical resistant booties, safety glasses, hard hat, and simple respirator. |
| When undressing PPE, what is the last item to take off? | Gloves |
