Chapter 12 - Personal Protective Equipment Flashcards
Who must provide PPE
Employer must provide PPE
hazard assessment
job hazard assessment must be completed and in writing and must be maintained by the employer - needed for PPE assessment
head protection
1910.135
prevents injury from falling or flying objects or my bumping head against a fixed object
must resist penetration and absorb shock of blow - may also prevent electrical shock
hard hat classification
three basic types
electrical, general, and conductive
hard hat safety zone
minimum of 1 to 11/4 in clearance between hard hat and suspension - important in absorption of an impact to hard hat
hard hat inspection and maintenance
cleaned and inspected - daily inspections for
cracked, torn or frayed suspension systems,
damaged cracked or perforated brims and shells,
flaking chalking or loss of surface gloss
discard after 5 years
head protection training
why necessary, how head protection will protect, limits of head protection, when protection must be worn, how to properly wear, how to adjust straps for safe fit, how to check for wear
eye protection must be provided if
potential for injury to the eyes or face from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation
minimum requirements for eye protection
adequate protection against particular hazards for which they are designed
reasonably comfortable when worn under the designated conditions
fit snugly without interfering with movement or vision
durable
capable of being disinfected
easily cleanable
kept clean in good repair
eye protection must be distinctly marked
shade number must be appropriate for work bein performed for protection from injurious light radiation
hearing protection
performed or moded earplugs should be individually fitted by a professional
waxed cotton, foam or fiberglass wool earplugs are self- forming foam or fiberglass wool earplugs are self-forming
disposable earplugs
should be used one time and then thrown awa
earmuffs
must seal around ear to be effective
hearing protectors must attenuate employee exposure to
90 dB for an 8hr time weighted average
NRR
noise reduction rating - when using NRR to assess hearing protector adequacy - subtract NRR from the measurement
training
required for all employees who are exposed to noise at or above 85 dB
repeated annually for each employee
must include
effects of noise on hearing
purpose of hearing protectors- advantages, disadvantages, and attenuation of various types
instructions on selection fit use and care
purpose of audiometric testing procedures
Respirators required-
where exposure levels exceed permissible exposure limit during the time period necessary
in maintenance and repair activities during brief or intermittent operations where exposures exceed permissible limits
in regulated areas
where employers have implemented all feasible engineering and work practice controls and such controls are not sufficient to reduce exposures to or below PEL
in emergencies
Respiratory Protection Standard
To control occupational diseases caused by breathing air contaminated with harmful dust, fogs, fumes, mists, gases, smokes, sprays, or vapors - where engineering control measures are not feasible
the employer is responsible for the respiratory program
Air purifying respirator
removes specific air contaminants by passing ambient air through the air purifying element
atmosphere supplying respirator
supplies user with breathing air from an independent source - includes supplied-air respirators and self contained breathing apparatus
assigned protection factor
protection factor assigned to respirator type
fit test
use of a protocol to qualitatively or quantitatively evaluate the fit of a respirator on an individual
powered air-purifying respirator
air purifying respirator that uses a blower to force the ambient air through the element to the inlet covering
Qualitative Fit Test
pass-fail test to assess the adequacy of respirator fit
