Emergency First Aid Measures

Critical first aid procedures for chemical exposure incidents and medical emergencies

🫁 Inhalation Exposure

Remove to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Keep warm. Get immediate medical attention.

🖐️ Skin Contact

Immediately wash skin with plenty of water for at least 20 minutes, while removing contaminated clothing and shoes. Get medical attention especially if irritation develops, persists, or symptoms of overexposure become apparent.

👁️ Eye Contact

Immediately flush eyes with plenty of water for at least 20 minutes, assuring adequate flushing of the eyes by separating the eyelids with fingers. Get immediate medical attention if irritation persists, or symptoms of overexposure become apparent.

🍽️ Ingestion/Swallowing

If swallowed, call a physician or poison control center immediately. Never give anything by mouth to an unconscious person. Do not induce vomiting unless instructed by medical personnel. Get medical attention.

Safe Handling & Storage Procedures

Industrial handling precautions, storage conditions, and workplace safety requirements

⚠️ Handling Precautions

• This product should be handled only by, or under the close supervision of, those properly qualified in the handling and use of potentially hazardous chemicals, who should take into account the fire, health and chemical hazard data.

• It should always be handled in an efficient fume hood or equivalent system.

• The user should consider that the toxicological and physiological properties of many compounds are not yet well determined and that new hazardous products may arise from reactions between chemicals.

• Care should be taken to prevent any chemical from coming into contact with the skin or eyes and from contaminating personal clothing.

🏪 Storage Conditions

• Store in a cool, dry, well ventilated area away from sources of heat and incompatible substances.

• Keep container tightly closed when not in use.

• Retest in 3 years.

🧼 General Hygiene Measures

Wash thoroughly after handling. Avoid contact with eyes and skin. Avoid inhaling vapor or mist.

Exposure Controls & Personal Protective Equipment (PPE)

Occupational exposure limits, engineering controls, and required safety equipment

🏭 Engineering Controls

Use appropriate engineering control such as process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Where such systems are not effective wear suitable personal protective equipment, which performs satisfactorily and meets OSHA or other recognized standards. Consult with local procedures for selection, training, inspection and maintenance of the personal protective equipment.

🧤 Hand Protection

Wear appropriate protective gloves. Consult glove manufacturers for glove permeability data.

👁️ Eye Protection

Wear appropriate protective glasses or splash goggles as described by 29 CFR 1910.133, OSHA eye and face protection regulation, or the European standard EN 166.

😷 Respiratory Protection

A NIOSH approved air-purifying respirator with an appropriate cartridge or canister may be permissible under certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited to airborne concentrations that are typically within 10 times the exposure limit. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air-purifying respirators may not provide adequate protection. A respiratory protection program that meets OSHAs 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirators use.

🦺 Skin/Body Protection

Wear suitable protective clothing to prevent contact with skin.

Chemical Stability & Reactivity Data
