FIRE AND EXPLOSION DATA
Flash Point: not available
Flammable limits: non flammable
Extinguishing media: N/A
Special Firing Fighting Procedure: Firefighters should wear full protective
clothing and OSHA/NIOSH self-contained breathing apparatus. Water fog will be
most effective for controlling HCL vapors.
Fire and explosion Hazards: Hydrochloric acid does not decompose at
temperatures below 1500 degrees C. It is non flammable; however flammable and potentially explosive hydrogen gas is generated from reaction with most metals.
STABILITY AND REACTIVITY
Chemical: Stable
Conditions to avoid: To prevent ignition of hydrogen gas
generated by muriatic acid, contact with most metals; smoking, flames and sparks
should not be permitted in storage or handling areas.
Hazardous Products of decomposition: Does not decompose
Polymerization: Will NOT Occur.
Incompatibility: Most metals, Alkalies, metallic oxides, amines, esters, and
certain other organics cause exothermic reactions, possibly violent. Carbonates
, cyanides, sulfides yield toxic gas. Water reactive materials such as sulfuric
acid, oleum, and acetic anhydride cause exothermic reaction.
Emergency Overview
Corrosive; May cause severe skin and eye irritation or chemical burns to
broken skin. Vapors extremely irritating to eyes and respiratory tract. HARMFUL
AND POTENTIALLY FATAL IF SWALLOWED.
INGESTION: Can cause corrosion of mucous membranes, severe esophageal burns
and perforation of esophagus or stomach.
INHALATION: Inhalation of vapors can cause bronchial irritation, coughing,
difficulty in breathing, nausea and pulmonary edema.
EYE CONTACT: Corrosive to the eyes; may cause severe and permanent damage.
SKIN CONTACT: Severe irritant; contact can produce blistering and eczema.
Avoid breathing vapors. Do not store near food , water , or feed. Protect
eyes, skin, and clothing from contact with this product.
FIRST AIDE MEASURES
INGESTION: If swallowed DO NOT induce vomit Immediately drink a large
quantity of water. Do not use acidic antidotes or sodium bicarbonate (baking
soda). Call a physician or poison control center immediately.
INHALATION: If exposed to excessive vapor levels, remove to fresh air and
seek medical attention if cough or other symptoms occur.
EYE CONTACT: Immediately flush eye with plenty of cool, running water. Remove
contact lenses if applicable, and continue flushing for at least 15 min. GET
medical attention immediately.
SKIN CONTACT: Flush affected skin area with copious amounts of water and wash
with soap and water. If irritation develops or persists, get medical attention.
Remove clothing and wash before reuse.
Personal Protective
RESPIRATOR: Not normally necessary; use NIOSH approved respirator for
concentrated vapors.
GOGGLES/FACE SHIELD: Required; goggles should be chemical splash type. Face
shield also helpful.
APRON: Recommended to avoid skin contact and protect clothing from damage.
GLOVES: Required; use impervious PVC or Neoprene with long gauntlet.
BOOT: Recommended to protect shoes and feet when using product for cleaning
floors.
