7. Handling and Storage
Handling: Use air conveying / mechanical systems for bulk transfer to storage. For manual handling of bulk
transfer, use mechanical ventilation to remove airborne dust from railcar, ship or truck. Use approved respiratory
protection when ventilation systems are not available. Selection of respirators is based on the dust cloud
generation. Keep material out of lakes, streams, ponds and sewer drains.
Avoid eye contact or prolonged skin contact. Avoid breathing dusts. When dissolving, add to water cautiously and
with stirring, solutions can get hot. Use good personal hygiene and housekeeping.
Storage: Store in a cool dry area, away from acids. Prolonged storage may cause product to cake from
atmospheric moisture.
8. Exposure Controls / Personal Protection
Engineering Controls: Where possible, provide general mechanical and/or local exhaust ventilation to
prevent release of airborne dust into the work environment. Eye wash facility should be provided in storage and
general work area.
Personal Protective Equipment:
Eyes and Face: For dusty or misty conditions, or when handling solutions where there is reasonable
probability of eye contact, wear chemical safety goggles and hard hat. Under these conditions, do not wear
contact lenses. Otherwise, appropriate eye and face protection equipment (ANSI Z87 approved) should be
selected for the particular use intended for this material. Safety glasses with side shields are recommended.
Respiratory: Whenever dust in the worker’s breathing zone cannot be controlled with ventilation or other
engineering means, workers should wear respirators or dust masks approved by NIOSH/MSHA, EU CEN or
comparable certification organization to protect them against airborne dust.
Hands, Arms, and Body: Wear long-sleeve shirt and trousers, and impervious gloves for routine product use.
Cotton gloves are sufficient for dry product. Wear impervious gloves when handling solutions.
Additional Exposure Guidelines: Federal guidelines treat the ingredient(s) in this product as a nuisance dust,
as no product-specific guidelines have been issued for exposure. As with all nuisance dusts, worker breathing
zone concentrations should be measured by validated sampling and analytical methods. The following limits
(OSHA and MSHA) apply to this material:
Particulates Not Otherwise Regulated:
OSHA (PEL/TWA): 15 mg/m
3
(total dust); 5 mg/m
3
(resp fraction)
MSHA (PEL / TWA): 10 mg/m
3
(total dust)
Avoid simultaneous exposure to soda ash and lime dust. In the presence of moisture (i.e. perspiration), the two
materials combine to form caustic soda (NaOH), which may cause burns.
The information noted above provides general guidance for handling this product. Specific work environments and material
handling practices will dictate the selection and use of personal protective equipment (PPE).
