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.

 

This product may contain crystalline silica, quartz (<1.0%) which is considered a hazard by inhalation.  IARC has classified crystalline silica as a carcinogenic to humans (Group 1).  Crystalline silica is also listed by NTP as a known human carcinogen.

 

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.

Section VI                                             Reactivity Data

 

Stability:                                                                                                                         Stable

Chemical Incompatibilities:   Hydrofluoric Acid

Conditions to avoid:             None in designed use. Avoid contact with hydrofluoric

acid.

Hazardous Decomposition Products:  May react with hydrofluoric acid to form toxic

     silicon tetrafluoride gas.

 

Section VII                          Precautions For Safe Handling and Use

 

Personal Protective Equipment:  Adequate protective devises, such as an N95 respirator,

                                             is recommended when the PEL is exceeded and / or

                                             when dust is present.

Gloves:  Not normally required.

Goggles:  Goggles to prevent dust from entering the eyes.

Engineering controls:  Local if necessary to maintain allowable PEL or TLV levels.

Leak and Spill Procedures:  Vacuum clean spillage.  Wet sweep or wash away.  Avoid

                                         Creating dust.

Waste Management:  Dispose in accordance with federal, state and local regulations.

Perlite is not considered a hazardous waste under RCRA (40CFR Part 261)

Handling Procedures: Repair or properly dispose of broken bags.  Maintain good

housekeeping procedures.

Storage Segregation Hazard Classes:  N/A

Special Shipping Instructions:  None

 

Section VIII                                         First Aid Measures

 

Skin:  Not absorbed by the skin.  May cause dryness.  Use moisture renewing lotions if

      dryness occurs.

Eyes:  May cause irritation or inflammations. Flush eyes with copious quantities of

water.  If irritation persists, call a physician.

Inhalation:  Acute inhalation can cause dryness of the nasal passages and congestion of

the upper respiratory tract.  Remove to fresh air.  Drink water to clear throat     and blow nose to evacuate dust.

Ingestion:  Short-term exposures not considered harmful.  Drink water to reduce bulk.
