Data Sheet (SDS) Template
This Appendix provides a generic template that can be used to develop an OSHA compliant SDS for Flue Gas Desulfurization (FGD) gypsum.
Comments have been included within the template to assist American Coal Ash Association (ACAA) members in populating the SDS appropriately. In general, items highlighted in yellow will require additional input from the SDS developer to identify/include the appropriate information. Other required information for populating the template may originate from the manufacturer/distributer or the FGD gypsum. The SDS Guidance Document can be used as a source of required information if it is not available here.
Note: Delete highlights and comments upon generation of an SDS using the template. Adjust Page Breaks as necessary to keep section, subsection or tabular information together.

First Aid Measures
|
4.1Description of First Aid Measures
Inhalation:
|
If product is inhaled and irritation of the nose or coughing occurs, remove person to fresh air. Get medical advice/attention if respiratory symptoms persist.
|
Skin Contact:
|
If skin exposure occurs, wash with soap and water.
|
Eye Contact:

|
Ingestion:
|
No specific first aid measures are required.
|
4.2Most Important Health Effects, Both Acute and Delayed
Acute effects: Acute exposure to FGD gypsum dust can dry and irritate the skin and cause dermatitis or eye irritation through mechanical abrasion.
Chronic effects: Chronic exposure to FGD gypsum may cause lung damage from repeated exposure. Chronic inhalation of dusts containing respirable crystalline silica may result in silicosis.
4.3Indication of Any Immediate Medical Attention and Special Treatment Needed
Seek first aid or call a doctor or Poison Control Center if contact with eyes occurs and irritation remains after rinsing. Get medical advice if inhalation of dust occurs and respiratory symptoms persist.

Suitable Extinguishing Media:
|
Product is not flammable. Use extinguishing media appropriate for surrounding fire.
|
Unsuitable Extinguishing Media:
|
Not applicable, the product is not flammable.
|
5.2Special Hazards Arising From the Substance or Mixture
Hazardous Combustion Products:

As with any fire, wear self-contained breathing apparatus (NIOSH approved or equivalent) and full protective gear.
|
Section 6
Accidental Release Measures
|
6.1Personal Precautions, Protective Equipment and Emergency Procedures
Personal precautions/Protective Equipment:
|
See Section 8.3 Individual Protective Measures. For concentrations exceeding Occupational Exposure Levels (OELs), use a self-contained breathing apparatus (SCBA).
|
Emergency procedures:
|
Use scooping, water spraying/flushing/misting or ventilated vacuum cleaning systems to clean up spills. Do not use pressurized air.
|
6.2Environmental Precautions
Environmental precautions:
|
Prevent contamination of drains or waterways and dispose according to local and national regulations.
|
6.3Methods and Material for Containment and Cleaning Up
Methods and materials for containment and cleaning up:
|
Do not use brooms or compressed air to clean surfaces. Use dust collection vacuum and extraction systems.
Large spills of dry product should be removed by a vacuum system. Dampened material should be removed by mechanical means and recycled or disposed of according to local and national regulations.
|
See Sections 8 and 13 for additional information on exposure controls and disposal.
Section 7
Handling and Storage
|
7.1Precautions for Safe Handling
Practice good housekeeping. Use adequate exhaust ventilation, dust collection and/or water mist to maintain airborne dust concentrations below permissible exposure limits (note: respirable crystalline silica dust may be in the air without a visible dust cloud).
Do not permit dust to collect on walls, floors, sills, ledges, machinery, or equipment. Maintain and test ventilation and dust collection equipment. In cases of insufficient ventilation, wear a NIOSH approved respirator for silica dust when handling or disposing dust from this product. Avoid contact with skin and eyes. Wash or vacuum clothing that has become dusty. Avoid eating, smoking, or drinking while handling the material.
7.2Conditions for Safe Storage, Including any Incompatibilities
Minimize dust produced during loading and unloading.

8.2Exposure Controls
8.2.1Engineering Controls
Provide ventilation to maintain the ambient workplace atmosphere below the occupational exposure limit(s). Use general and local exhaust ventilation and dust collection systems as necessary to minimize exposure.
8.2.2Personal Protective Equipment (PPE)
Respiratory protection:
|
Wear a NIOSH approved particulate respirator if exposure to airborne particulates is unavoidable and where occupational exposure limits may be exceeded. If airborne exposures are anticipated to exceed applicable PELs or TLVs, a self-contained breathing apparatus or airline respirator is recommended.
|
Eye and face protection:
|
If eye contact is possible, wear protective glasses with side shields. Avoid contact lenses.
|
Hand and skin protection:
|
Wear gloves and protective clothing. Wash hands with soap and water after contact with material.

|
Germ cell mutagenicity
|
Several in vitro and in vivo mutagenicity assays determined that calcium sulfate, dihydrate was non-mutagenic, with and without metabolic activation.
|
Carcinogenicity
|
No data on calcium sulfate, dihydrate. Carcinogenic studies were not conducted based on the non-neoplastic effects noted in the oral and inhalation repeated dose studies as well as the negative mutagenicity assays.
Respirable crystalline silica has been identified as a carcinogen by NTP and IARC.
|
Reproductive toxicity
|
No significant developmental or reproductive toxicity were identified in rabbits after exposure to either calcium sulfate, dihydrate or calcium sulfate, dihydrate.
|
Specific Target Organ Toxicity–Single Exposure
|
Acute toxicity testing did not result in direct organ toxicity after a single exposure to calcium sulfate, dihydrate. However, as the form of tested was not indicated, FGD gypsum dust may result in mechanical irritation.
|
Specific Target Organ Toxicity–Repeated Exposure
|
A repeat dose oral toxicity study (35-45 days) with calcium sulfate, dihydrate conducted using rats reported a NOAEL for males of 100 mg/kg/day on the basis of decreased total protein, albumin, blood urea nitrogen, and creatinine levels observed at the 300 and 1,000 mg/kg/day dose groups. No effects were observed in females.
