Section V                                            Health Hazards

 

Summary:  Perlite is a naturally occurring volcanic glass consisting of fused sodium* potassium * aluminum silicate.  OSHA has classified perlite as a Particulate Not Otherwise Regulated (PNOR), which has the same Permissible Exposure Limit (PEL) as that used for nuisance and inert dusts.  Although there are no published reports of adverse health effects from exposure to perlite dust, dust levels should be maintained below the OSHA PEL for PNORs and respirators should be used when airborne dust is present.  Excessive inhalation over long periods of time may cause harmful irritation.  Perlite is considered a nuisance dust by ACGIH.

 

Medical conditions which may be aggravated:  pre-existing upper respiratory and lung

disease such as, but not limited to bronchitis, emphysema and asthma.

Target Organs:  Lungs, Eyes

Route of Entry:  Inhalation, dust contact with eyes.

Acute Health Effects: Transitory upper respiratory irritant.  May cause coughing or

          Throat irritation.

Chronic Health Effects:  Excessive inhalation of any mineral dust can overload the

          lung clearance mechanism.
