First-aid measures

The potential for hydrogen fluoride formation exists with every exposure, therefore its toxicity must also be considered. Seek
medical advice. If breathing has stopped or is labored, give assisted respirations. Supplemental oxygen may be indicated. If the heart
has stopped, trained personnel should begin cardiopulmonary resuscitation immediately.

Eye contact : Rinse immediately with plenty of water also under the eyelids for at least 20 minutes. Remove contact lenses.

Skin contact : Wash off immediately with plenty of water for at least 20 minutes. Immediately remove contaminated clothing, and any extraneous
chemical, if possible to do so without delay.

Ingestion : Never give anything by mouth to an unconscious person. If a person vomits when lying on his back, place him in the recovery position.

Inhalation : If breathing has stopped or is labored, give assisted respirations. Supplemental oxygen may be indicated. If the heart has stopped,
trained personnel should begin cardiopulmonary resuscitation immediately. Move to fresh air.

Fire-fighting measures

Suitable extinguishing media:
Alcohol-resistant foam.
Carbon dioxide (CO2).
Dry chemical.
Dry sand.
Limestone powder.

Specific hazards : Incomplete combustion may form carbon monoxide. Potential dust explosion

Accidental release measures

Personal precautions :
Wear suitable protective clothing, gloves and eye/face
protection. Use self-contained breathing apparatus and
chemically protective clothing. Evacuate personnel to safe areas.
Methods for cleaning up :
Approach suspected leak areas with caution. Place in
appropriate chemical waste container.
Additional advice:

Open enclosed spaces to outside atmosphere. If possible, stop
flow of product.


Handling and storage

Handling
Avoid dust formation. Do not breathe vapors/dust. Emergency showers and eye wash stations should be
readily accessible. Adhere to work practice rules established by government regulations. Avoid contact
with eyes. Use only in well-ventilated areas. Use personal protective equipment. When using, do not eat,
drink or smoke.
Storage
Keep containers tightly closed in a dry, cool and well-ventilated place. Store at room temperature in the
original container. Store under a nitrogen atmosphere. Keep away from heat.

Exposure controls / personal protection

Engineering measures
Provide readily accessible eye wash stations and safety showers. Provide natural or explosion-proof
ventilation adequate to ensure concentrations are kept below exposure limits.
Personal protective equipment
Respiratory protection
:
Respirator must be worn if exposed to dust. Wear appropriate
respirator when ventilation is inadequate. Use a NIOSH/MSHA
approved full-face respirator with acid gas cartridges.
Hand protection: Impervious gloves.

The breakthrough time of the selected glove(s) must be greater than the
intended use period.

Eye protection: Dust resistant safety goggles.
Chemical resistant goggles must be worn.
Skin and body protection : Long sleeve shirts and trousers without cuffs.
Special instructions for Provide readily accessible eye wash stations and safety showers.
protection and hygiene : Wash at the end of each workshift and before eating, smoking or using the
toilet.
