Magnesium Hydroxide 1309-42-8 99 - 100% Yes
Inhalation: May cause irritation to the respiratory tract. Symptoms may
include coughing, sore throat, labored breathing, and chest pain.
Ingestion: May cause irritation to digestive tract. Excessive amounts of
magnesium can cause CNS depression and respiratory paralysis which can be fatal.
Skin Contact: May cause irritation with redness and pain.
Eye Contact: May cause irritation, redness and pain.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: Persons with impaired kidney
function may be more susceptible to the effects of the substance.
Inhalation: Remove to fresh air. Get medical
attention for any breathing difficulty.
Ingestion: Give large amounts of water to drink. Never give anything by
mouth to an unconscious person. Get medical attention.
Skin Contact: Immediately flush skin with plenty of water for at least 15
minutes. Call a physician if irritation develops.
Eye Contact: In case of contact, immediately flush eyes with plenty of
water for at least 15 minutes, lifting upper and lower eyelids occasionally.
Call a physician if irritation persists.
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire.
Special Information: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. Local exhaust
ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where
exposure to dust or mist is apparent and engineering controls are not feasible,
a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a
NIOSH type R or P filter. For emergencies or instances where the exposure levels
are not known, use a full-face positive-pressure, air-supplied respirator.
WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Safety glasses. Maintain eye wash fountain and
quick-drench facilities in work area.
