How to Prevent Noise Find quieter ways

Move equipment away from the work zone when

possible

Shield loud power equipment in the work zone

Buy Quiet

Turn off equipment when not in use

Block itMove it.Reduce it


13/41

Find Quieter Ways

Examples:

Maybe you can use a hydraulic cutter or

Porta-band in place of an abrasive saw,especially when cutting metal

Or, instead of punching holes in decking or

sheet metal, use a drill. Consider alternative types of fasteners topowder actuated tools


14/41

Move Noisy Equipment

An air compressor does not have to be

within arms length. It can be placed

hundreds of feet away. All it takes is oneextra length of air hose.

What could be done here?


16/41


17/41

Buy Quiet

Example:

When it is time to buy new equipment or

tools, ask the employer to think about whatis least noisy. Develop a noise limit policy.

Find ways to retrofit existing equipment to

make it less noisy, such as installingmufflers.

Maintain equipment


18/41

Turn it Off

Turn off power equipment when it is not in

use


19/41

Reducing Noise from Other

Trades Job site meetings (Risk Chart & Weekly

Action Plan Sheets)

Know the noisy tasks

Schedule noisy tasks for off hours

Ask the employer to check noise levels of

different tasks

Care and Maintenance

Foam plugs: Use them when they look like theyare new, or get new ones

Earmuffs: Wipe down with a damp cloth, orremove the cushions and wash in soapy water.Cushions should be replaced if torn or cracked.Replace entire muff if headband is sprung.

Custom: Replace every 3-5 years. Wash in mildsoapy water.

Pre-molded: Replace the earbuds if they are dirtyor damaged.

Problems in getting hearingconservation into construction

Mobile work force

Companies

mandate hard hats& safety glasses,not as consistentabout ear plugs &

muffs The ears do not

bleed, can not see

the injury

Lusk et al., University ofMichigan; Melamed et al,Israeli study; NIOSH

28/41

Reasons workers do notuse hearing protectors:

Fear of not hearing warning signals &voices (especially if hearing protection

is more than needed) Uncomfortable to wear all day

Benefit not readily apparent (hearing

loss is gradual) More immediate hazards on job site

HEARING LOSS Caused by exposure to harmful noise

levels

Hearing Conservation in

Washington State WISHA requires that employers provide a

hearing conservation program to employees

if they are exposed to 85 dB or more for anaverage of 8-hours

Transient workforce makes it difficult

Build It Smart proposes an industry-widehearing testing program
