High efficiency particulate air (HEPA) filter Immediately dangerous to life of health (IDLH) Negative pressure respirator Oxygen deficient atmosphere Positive pressure respirator Powered air-purifying respirator Self-contained breathing apparatus (SCBA) Supplied-air respirator (SAR) Definitions
General Information • Why respirator is necessary • How improper fit, use, or maintenance can effect the purpose of the respirator
General Information • Filter differences • Organic Chemical Filters • Dust Filters • Dust Masks • USE THE RIGHT FILTER!
Oxygen level in atmosphere must be between 19.5% and 21% Will only work with corresponding filters or cartridges Can protect you from hazardous levels of materials If worn properly and in the right atmosphere, respirators can save your life Limitations and Capabilities
Inspection, Donning, Doffing, Use, and Checking Seals • Always inspect respirator before donning • Check integrity of seals and cartridges before putting on respirator
Maintenance and Storage • Cleaning and disinfecting • Storage • Inspection
The following are signs or symptoms that may prevent the use of a respirator: Seizures Claustrophobia Asthma Emphysema Pneumonia Collapsed Lung Lung Cancer Broken Ribs Chest Injuries/Surgeries Any other lung problems Heart or Circulation problems Anxiety Medical Signs and Symptoms
A worker is exposed to 50 parts per million (ppm) of Benzene. Benzene has a Permissible Exposure Level (PEL) of 10 ppm. The worker wants to use a half-mask, air-purifying organic vapor cartridge respirator. 10 (Protection factor for half-mask respirator) X 10 (PEL of 10 parts per million for Benzene) = 100 (Max. permissible safe concentration for this situation) Scenarios
A worker will be exposed to 600 micrograms per cubic meter of lead during a paint removal operation. Lead dust has a PEL of 50 micro grams per cubic meter. The worker wants to use a disposable, air-purifying, high efficiency particulate air (HEPA) respirator. 5 (Protection factor for a disposable mask) X 50 (PEL of 50 micrograms/cubic meter for lead) = 250 (Max. permissible safe concentration for this situation) Scenarios
