Read MSDS for details.
Emergency Overview : Gypsum is a solid , white , odorless powder . It is not
combustible or explosive . Short period exposure to the powder presents little hazard .
Potential Health Effects :
Eye Contact : Airborne dust may cause immediate irritation or inflammation . Eye
contact with large amounts of gypsum may cause eye irritation , redness , and abrasions
.Eye exposures require immediate first aid .
Skin Contact : Gypsum may cause dry skin , discomfort , and irritation .
Inhalation : ( acute ) Breathing dust may cause nose , throat or lung irritation ,
including choking , depending on the degree of exposure .
( chronic ) Risk of injury depends on duration and level of exposure .
Silicosis : This product may contains crystalline silica . Prolonged or repeated inhalation
of respirable crystalline silica can cause silicosis , a seriosly disabling and fatal lung
disease .
Carcinogenicity : Gypsum is not listed as a carcinogen by IARC or NTP ; however ,
gypsum contains trace amounts of crystalline silica and hexavalent chromium which are
classified by IARC and NTP as known carcinogens .
Autoimmune Disease : Some studies show that exposure to respirable crystalline silica (
without silicosis ) or that the disease silicosis may be associated with the increased
incidence of several autoimmune disorders such as scleroderma ( thickening of the skin )
, systemic lupus erythematosus , rheumatoid arthritis and diseases affecting the kidneys .
Tuberculosis : Silicosis increases the risk of tuberculosis .
Renal Disease : Some studies shown an increased incidence of chronic kidney disease
and end-stage renal disease in workers exposed to respirable crystalline silica .
Ingestion : It is completely forbidden to ingest gypsum . Although ingestion of small
amounts of gypsum is not known to be harmful , but ingestion of large quantities can
cause an obstruction causing pain and distress in the digestive tract .
Medical Conditions Aggravated by Exposure : Individuals with lung disease ( e.g.
bronchitis , emphysema , COPD , pulmonary disease ) or sensitivity to hexavalent
chromium can be aggravated by exposure .
Section 4 : FIRST AID MEASURES
Eye Contact : Rinse eyes thoroughly with water for at least 15 minutes , including under
lids , to remove all particles . Remove contact lenses ( if applicable ) . Seek medical
attention for abrasions and burns .
Skin Contact : Wash with cool water and a pH neutral soap or a mild skin detergent .
Seek medical attention for rash , irritation , dermatitis and prolonged unprotected
exposures to wet gypsum .
Inhalation : Move person to fresh air . Seek medical attention for discomfort or if
coughing or other symptoms do not subside .
Ingestion : Do not induce vomiting . Gypsum is non-hazardous and no harmful effects
are expected upon ingestion of small amounts . Larger amounts may cause abdominal
discomfort or possible obstruction of the digestive tract . Seek medical attention if
problems persist .
Section 5 : FIREFIGHTING MEASURES
Flammable Properties
- Not flammable or combustible , but may become involved in a fire with other materials
.
Extinguishing media
- Dry chemical , foam , water , fog or spray .
Protection of firefighters
- Standard protective equipments and precautions .
Fire and Explosion Hazards
- None .
Hazardous Combustion Products
- None .
- Above 1450 C , material can decompose and release sulfur dioxide ( SO2 ) and oxides
of calcium & carbon .
Section 6 : ACCIDENTAL RELEASE MEASURES
General recommendations
Place spilled material into a container . Avoid actions that cause the gypsum to become
airborne . Avoid inhalation of gypsum and contact with skin . Wear appropriate
protective equipment as described in Section 8 . Do not wash gypsum down sewage and
drainage systems or into bodies of water ( e.g. streams ) .
On Land
Prevent spread of material and keep dust level down as much as possible . Scoop up
material and all contaminated soil for later disposal .
In Water
Use vacuum techniques and containment devices to prevent spread and remove material
from water source for later disposal .
Section 7 : HANDLING AND STORAGE
General :
Avoid dust contact with eyes . Wear the appropriate eye protection against dust .
Minimize dust generation and accumulation . Avoid breathing dust . Wear the appropriate
respiratory protection against dust in poorly ventilated areas . Avoid contact with skin
and clothing . Use good safety and industrial hygiene practices .
Handle with care and use appropriate control measures . Keep bulk gypsum dry until
used .
Engulfment hazard . To prevent burial or suffocation , do not enter a confined space ,
such as silo , bin , bulk truck , or other storage container or vessel that stores or contains
gypsum . Gypsum can buildup or adhere to the walls of a confined space . The gypsum
can release , collapse or fall unexpectedly .
Do not stand on stockpiles of gypsum , they may be unstable . Use engineering controls (
e.g. wetting stockpiles ) to prevent windblown dust from stockpiles , which may cause
the hazards described in Section 3 .
Follow traditional building practices ; such as management of water away from the
interior of the structure to avoid the growth of mold , mildew and fungus . Remove any
building products suspected of being exposed to sustained moisture and considered
conducive to mold growth from the jobsite .
Usage :
Cutting , crushing , sanding or grinding drywall , hardened cement , concrete or other
crystalline silica-bearing materials will release respirable crystalline silica . Use all
appropriate measures of dust control or suppression , and Personal Protective Equipment
( PPE ) described in Section 8 below .
Clothing :
Promptly remove and launder clothing that is dusty or wet with gypsum . Thoroughly
wash skin after exposure to gypsum .
Storage :
Store in a cool , dry ventilated area away from sources of heat , moisture . Protect product
from physical damage .
Protect from weather and prevent exposure to sustained moisture .
Avoid actions that cause the gypsum to become airborne during clean-up such as dry
sweeping or using compressed air . Use HEPA vacuum or thoroughly wet with water to
clean-up dust . Use PPE described in Section 8 below .
Storage Temperature :
Unlimited .
Storage pressure :
Unlimited .
Section 8 : EXPOSURE CONTROLS AND PERSONAL PROTECTION
Engineering Controls : Use local exhaust or general dilution ventilation or other
suppression methods to maintain dust levels below exposure limits .
Personal Protective Equipment ( PPE ) :
Respiratory Protection : Under ordinary conditions no respiratory protection is required .
Wear a NIOSH approved respirator that is properly fitted and is in good condition when
exposed to dust above exposure limits .
Eye Protection : Wear approved safety glasses or safety goggles when handling dust or
wet gypsum to prevent contact with eyes . Wearing contact lenses when using gypsum ,
under dusty conditions , is not recommended .
Skin Protection : Wear gloves , boot covers and protective clothing , when necessary , to
prevent skin contact . Do not rely on barrier creams , in place of impervious gloves .
Remove clothing and protective equipment that becomes saturated with wet gypsum and
wash exposed areas .
Clothing : Wear appropriate clothing to prevent contact .
