First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

If unconscious place in recovery position and seek medical advice. If symptoms persist, call a physician.

Skin contact

If on skin, rinse well with water. If on clothes, remove clothes.

Symptoms: If skin irritation persists, call a physician. Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficulty.

Eye contact

In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Continue rinsing eyes during transport to hospital. Remove contact lenses.

Symptoms: Small amounts splashed into eyes can cause irreversible tissue damage and blindness. If eye irritation persists, consult a specialist.

Ingestion

Keep respiratory tract clear. Never give anything by mouth to an unconscious person. Take victim immediately to hospital.

Immediate Medical Attention

Consult a physician. Seek medical advice. Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficulty. Take victim immediately to hospital.

Medical Treatment

Consult a physician. Seek medical advice. Consult a specialist.

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Adequate ventilation to control airborned concentrations below the exposure guidelines/limits. Consider the potential hazards of this material (see Section 2), applicable exposure limits, job activities, and other substances in the work place when designing engineering controls and selecting personal protective equipment. If engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal protective equipment listed below is recommended. The user should read and understand all instructions and limitations supplied with the equipment since protection is usually provided for a limited time or under certain circumstances.

Hands

The suitability for a specific workplace should be discussed with the producers of the protective gloves. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. Also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion, and the contact time. Gloves should be discarded and replaced if there is any indication of degradation or chemical breakthrough.

Eyes

Eye wash bottle with pure water. Wear face-shield and protective suit for abnormal processing problems. Tightly fitting safety goggles.

Respiratory

Wear a NIOSH approved respirator that provides protection when working with this material if exposure to harmful levels of airborne material may occur, such as:. Wear a supplied-air NIOSH approved respirator unless ventilation or other engineering controls are adequate to maintain minimal oxygen content of 19.5% by volume under normal atmospheric pressure. Air-Purifying Respirator for Organic Vapors. Use a positive pressure, air-supplying respirator if there is potential for uncontrolled release, exposure levels are not known, or other circumstances where air-purifying respirators may not provide adequate protection.

Skin/Body

Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the specific work-place. Wear as appropriate:. Complete head face and neck protection. Rubber apron. Footwear protecting against chemicals.
