First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove to fresh air. If not breathing, give artificial respiration. Get medical attention if symptoms occur.

Symptoms: trouble breathing, dizziness, lightheadedness, chest pain

Skin contact

Wash off immediately with plenty of water for at least 15 minutes. If skin irritation persists, call a physician.

Symptoms: allergic skin reaction, rash, itching, swelling, tingling of the hands and feet, flushing

Eye contact

Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.

Ingestion

Clean mouth with water and drink afterwards plenty of water. Get medical attention if symptoms occur.

Medical Treatment

Treat symptomatically.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Water spray, carbon dioxide (CO2), dry chemical, alcohol-resistant foam.

Unsuitable media

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Wear personal protective equipment/face protection. Avoid ingestion and inhalation. Avoid dust formation. Ensure adequate ventilation. Do not get in eyes, on skin, or on clothing.

Storage

Keep containers tightly closed in a dry, cool and well-ventilated place.

Hygiene

Handle in accordance with good industrial hygiene and safety practice. Keep away from food, drink and animal feeding stuffs. Do not eat, drink or smoke when using this product. Remove and wash contaminated clothing and gloves, including the inside, before re-use. Wash hands before breaks and after work.

Fire prevention

Keep away from heat, sparks and flame.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Ensure that eyewash stations and safety showers are close to the workstation location. Ensure adequate ventilation, especially in confined areas. Use explosion-proof electrical/ventilating/lighting equipment. Wherever possible, engineering control measures such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release or contact, and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source

Hands

Protective gloves. Glove material: Natural rubber, Nitrile rubber, Neoprene, PVC. Breakthrough time: See manufacturers recommendations. EU standard: EN 374 (minimum requirement).

Eyes

Wear safety glasses with side shields (or goggles) (European standard - EN 166)

Respiratory

If inhalation exposure is likely or if irritation or other symptoms are experienced, wear a NIOSH/MSHA or European Standard EN 149 approved respirator. Large scale/emergency use: Use a NIOSH/MSHA or European Standard EN 136 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended Filter type: Particulates filter conforming to EN 143. Small scale/Laboratory use: Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended half mask: Particle filtering: EN149:2001. When RPE is used a face piece Fit Test should be conducted

Skin/Body

Long sleeved clothing.
