let's start the lesson about hazardous

materials the key points

are employee exposure to silica dust

brethable quartz must not exceed 0.1

microgram cubic meter averaged over an

8-hour

workshift silicosis can disable a person

in many ways making breathing difficult

and painful silicosis may also cause

death or turn into lung cancer symptoms

usually associated ated with silicosis

include loss of appetite fevers and body

weight

loss exposure by inhaling loose asbestos

fibers can cause disabling or fatal

diseases such as gastrointestinal cancer

cancers of the lung or lung cavity

lining and severe lung impairment

asbestosis the symptoms of these

diseases generally do not appear for 20

or more years after initial

exposure short-term exposure must also

be limited to not more than one fiber

per cubic meter averaged over 30 minutes

rotation of employees to achieve

compliance with either permissible

exposure limit PL is

prohibited even workers families and

friends can be at risk as asbestos can

often be carried on clothing it is

important to note that workers are only

sometimes told they are working around

asbes and even single exposures to very

low doses of fibers can result in

harm no employee may be exposed to MDA

above the permissible exposure limit PL

of 10 parts per billion ppb as an 8h

hour time weighted average TW wa or

above a short-term exposure limit STL of

100 ppb over a 15minute sampling

period decontamination areas must also

be established outside of but as near as

practical to the regulated area for

workers materials and Equipment

contaminated with MDA the

decontamination area must include

equipment storage wash and clean change

areas lastly lead is most commonly taken

into the body by inhalation when workers

breathe and Lead is dust fume or Mist

their lungs and upper respiratory tract

absorb the lead into the body they can

also absorb lead through the digestive

system if it enters the mouth and is

ingested now look at the study
