Most important symptoms/effects, acute and delayed
Inhalation of vapors or mist causes burning sensation of nose and throat, and lung irritation with coughing; prolonged or excessive exposure could cause vomiting and severe coughing. Ingestion causes blistering and burns of mouth and stomach. Contact with eyes or skin causes blistering and burns. (USCG, 1999)
Excerpt from ERG Guide 140 [Oxidizers]: Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
no data available
SECTION 5: Firefighting measures
Suitable extinguishing media
Combat fires from safe distance or protected location. flood discharge area with water. cool exposed containers with water. aqueous soln
Specific hazards arising from the chemical
Behavior in Fire: Above 160°C (320°F) will react with combustible material and increase intensity of fire. Containers may explode. (USCG, 1999)
Excerpt from ERG Guide 140 [Oxidizers]: These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard. (ERG, 2016)
Special protective actions for fire-fighters
In case of fire in the surroundings: water in large amounts, water spray. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

SECTION 10: Stability and reactivity
Reactivity
May explode on heating. Decomposes on heating. This produces toxic and corrosive fumes. The substance is a strong oxidant. It reacts violently with combustible and reducing materials, organic materials and strong bases. This generates fire and explosion hazard. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). The acid is unstable if the concentration is over 72%; may explode by shock or concussion when dry or drying. Mixtures with combustible material (such as paper) may ignite spontaneously at room temperature.
Chemical stability
VOLATILE
Possibility of hazardous reactions
AQ ACID...MAY DEFLAGRATE IN CONTACT WITH OXIDIZABLE SUBSTANCES. /AQUEOUS SOLN/PERCHLORIC ACID, [> 50% BUT <= 72% STRENGTH] is a solution of a strong oxidizing acid. May react vigorously or deflagrate when mixed with oxidizable material [Merck]. This includes (but is not limited to) alcohols, amines, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols [Bretherick 1979. p.174]. Perchloric acid ignites on contact with sulfinyl chloride. (Bailar, 1973, Vol. 2, 1442).

Other Information
DO NOT use perchloric acid in a hood designed for other purposes.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.Rinse contaminated clothing with plenty of water because of fire hazard.NEVER pour water into this substance; when dissolving or diluting always add it slowly to the water.
