Week 9 personal protective equipment Flashcards
If employees can change the way they do their jobs and the exposure to the potential hazard can be removed….. then the hazard can be eliminated through _____.
work practice control
engineering controls
Initial design specifications Substitute less harmful material Change process Enclose process Isolate process
An employer must
◦ Assess workplace for hazards ◦ Provide PPE ◦ Determine when to use ◦ Provide PPE training for employees and instruction in proper use
employee must
Use PPE in accordance with training received and other instructions Inspect daily and maintain in a clean and reliable condition
training includes
Why it is necessary How it will protect them What are its limitations When and how to wear How to identify signs of wear How to clean and disinfect What is its useful life & how is it disposed
when eye protection must be used
Dust and other flying particles, such as metal shavings or sawdust Corrosive gases, vapors, and liquids Molten metal that may splash Potentially infectious materials such as blood or hazardous liquid chemicals that may splash Intense light from welding and lasers
eye protection for employees that wear glasses
Prescription glasses with side shields and protective lenses Goggles that fit comfortably over corrective glasses without disturbing the glasses Goggles that incorporate corrective lenses mounted behind protective lenses
Made with metal/plastic safety frames Most operations require side shields Used for moderate impact from particles produced by jobs such as carpentry, woodworking, grinding, and scaling
safety glasses
Protects eyes and area around the eyes from impact, dust, and splashes Some goggles fit over corrective lenses
googles
Full face protection Protects face from dusts and splashes or sprays of hazardous liquids Does not protect from impact hazards Wear safety glasses or goggles underneath
safety shields
Protects eyes against burns from radiant light Protects face and eyes from flying sparks, metal spatter, & slag chips produced during welding, brazing, soldering, and cutting
welding shields
When it’s not feasible to reduce the noise or its duration -
use ear protective devices
When Must Hearing Protection be Provided?
After implementing engineering and work practice controls. When an employee’s noise exposure exceeds an 8-hour time-weighted average (TWA) sound level of 90 dBA.
when must fire protection be provided
Heavy objects such as barrels or tools that might roll onto or fall on employees’ feet Sharp objects such as nails or spikes that might pierce ordinary shoes Molten metal that might splash on feet Hot or wet surfaces Slippery surfaces
Impact-resistant toes and heat resistant soles protect against hot surfaces common in roofing and paving Some have metal insoles to protect against puncture wounds May be electrically conductive for use in explosive atmospheres, or nonconductive to protect from workplace electrical hazards
safety shoes
Burns Bruises Abrasions Cuts Punctures Fractures Amputations Chemical Exposures
when must hand protection be provided?
protects against solvents, harsh chemicals, fats and petroleum products and also provides excellent resistance to cuts and abrasions.
Nitrile rubber gloves
provides the highest permeation resistance to gas or water vapors
butly gloves
protects against cuts, slashes, and abrasion
kevlar gloves
protects against cuts and lacerations
stainless steal mesh gloves
Intense heat Splashes of hot metals and other hot liquids Impacts from tools, machinery, and materials Cuts Hazardous chemicals Radiation
Major causes of body injuries
The types of body protection
◦ Vests ◦ Aprons ◦ Jackets ◦ Coveralls ◦ Full body suits
Written standard operating procedures for respirators.
◦ Proper selection, use and care of respirators; ◦ Possible emergency and routine uses of respirators must be anticipated and planned for; ◦ Safe use in dangerous atmospheres that might be encountered.
Respirators must be selected:
On the basis of hazards to which the workers are exposed;◦ According to OSHA guidelines ◦ NIOSH Approved ◦ Fit tested by a qualified individual
Two types of respiratory protection
◦ Air Purifying ◦ Air Supplied
Air purifying respirators
Must be equipped with a NIOSH approved Filter
Respirators can be classified as either……
◦ Negative pressure ◦ Positive pressure
Negative Pressure Air Purifying Respirators
◦ Half Face Respirator ◦ Full Face Respirator
A facepiece that fits over the nose and under the chin. Sizes from small to extra large Variety of manufactures. Secures by two straps ◦ One goes over the crown ◦ Around the neck
Half face respirators
Facepiece that covers the entire face from the top of the forehead to below the chin. Secured by three straps ◦ One goes over the crown ◦ One pulls the top of th respirator up and tight to the face ◦ Other around the neck. Provides effective eye protection.
full face respirator
Air is blown into a tight fitting face piece ◦ Small fan ◦ Continuous flow of air ◦ Battery operated ◦ Filters or cartridges worn on: Belt Face piece
Power Air Purifying Respirator (PAPR)
Air is blown into a tight fitting facepiece ◦ Supplies minimum of Grade D air ◦ Compressed air cylinders ◦ Air compressor ◦ Combination SAR may have an egress cylinder a small cylinder of compressed air usually worn on the workers belt. Used when primary air source fails
Supplied Air Respirator (SAR)
Air is blown into a tight fitting facepiece ◦ Supplies minimum of Grade D air ◦ Compressed air cylinders
SCBA
Chemical challenge ◦ I.e., irritant smoke, saccharin mist, Bitrex, or banana oil Wearer is asked to move and speak during the test to simulate the fit during actual working conditions. If the wearer detects the substance by irritation, smell, or taste, the mask doesn’t fit.
Quantitative fit test
An assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirato
Quantitative Fit Test (QNFT)
Assess the workplace for hazards Use engineering and work practice controls to eliminate or reduce hazards before using PPE Select appropriate PPE to protect employees from hazards that cannot be eliminated Inform employees why the PPE is necessary, how and when it must be worn Train employees how to use and care for their PPE, including how to recognize deterioration and failure Require employees to wear selected PPE
Employers must implement a PPE program where they
