General Description
An odorless, light-gray to glassy-black solid. A naturally occurring aluminosilicate rock. May contain trace amounts of crystalline silica dust, a chronic health hazard by inhalation.

The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.

Health Hazard
Excerpt from NIOSH Pocket Guide for Perliteexternal link:

Exposure Routes: Inhalation, skin and/or eye contact

Symptoms: Irritation eyes, skin, throat, upper respiratory system

Target Organs: Eyes, skin, respiratory system (NIOSH, 2023)
Reactivity Profile
PERLITE is non-flammable and non-combustible. Mostly chemically inert. Soluble in hot concentrated alkali and HF. Moderately soluble (<10%) in 1 molar NaOH. Slightly soluble in dilute strong acids. Very slightly soluble in water or weak acids. No chemical incompatibilities reported. When heated to a sufficiently high temperature, it expands to between four and twenty times its original volume as its 2-6% by weight of loosely bound water boils away. When quickly heated to above 1600 degrees F, pops like popcorn as its water vaporizes. Expanded perlite is a fluffy, white particulate.

Protective Clothing
Excerpt from NIOSH Pocket Guide for Perliteexternal link:

Skin: No recommendation is made specifying the need for personal protective equipment for the body.

Eyes: No recommendation is made specifying the need for eye protection.

Wash skin: No recommendation is made specifying the need for washing the substance from the skin (either immediately or at the end of the work shift).

Remove: No recommendation is made specifying the need for removing clothing that becomes wet or contaminated.

Change: No recommendation is made specifying the need for the worker to change clothing after the workshift. (NIOSH, 2023)

First Aid
Excerpt from NIOSH Pocket Guide for Perliteexternal link:

Eye: IRRIGATE IMMEDIATELY - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately.

Breathing: FRESH AIR - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. Other measures are usually unnecessary. (NIOSH, 2023)

The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds The information in CAMEO Chemicals comes from a variety of data sources.

Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
