Personal Protective Equipment (PPE)
Respiratory Protection

Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).


Respirators should be used only under any of the following circumstances:

  • As a last line of defense (i.e., after engineering and administrative controls have been exhausted).

  • When Permissible Exposure Limit (PEL) has exceeded or when there is a possibility that PEL will be exceeded.

  • Regulations require the use of a respirator.

  • An employer requires the use of a respirator.

  • There is potential for harmful exposure due to an atmospheric contaminant (in the absence of PEL)

  • As PPE in the event of a chemical spill clean-up process

Lab personnel intending to use/wear a respirator mask must be trained and fit-tested by EH&S. This is a regulatory requirement. (http://www.asu.edu/uagc/EHS/documents/asu_respriatory_protection_plan.pdf)


Hand Protection

Handle with gloves. Use proper glove removal technique to avoid skin contact with this product. Nitrile gloves are recommended.


NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with sodium chlorate.

Eye Protection


  • Wear chemical splash goggles with side shields to protect from splash hazards and chemical vapors.


Skin & Body Protection


  • Fire/flame resistant lab coat

  • Full-length pants

  • Closed-toe rubber or leather shoes


Hygiene Measures
Avoid contact with skin, eyes, and clothing. Wash hands before breaks and immediately after handling the product.
Engineering Controls
All operations involving sodium chlorate should be handled with adequate ventilation to keep airborne concentrations below permissible exposure limits.
First Aid Procedures
If inhaled… Move to fresh air. If the person is not breathing, give artificial respiration. Avoid mouth to mouth contact. If breathing is difficult, give oxygen. Seek immediate medical attention. Call 911 from a campus phone or (480) 965-3456. Call EH&S at (480) 965-1823.
In case of skin contact… Remove all contaminated clothing. Immediately (within seconds) flush affected area for FIFTEEN (15) minutes. Seek immediate medical attention. Call 911 from a campus phone or (480) 965-3456 from a cell phone. Call EH&S at (480) 965-1823.
In case of eye contact… Remove any contact lenses. Use nearest emergency eyewash immediately for at least FIFTEEN (15) minutes. Seek immediate medical attention and continue eye rinse during transport to hospital. Call 911 from a campus phone or (480) 965-3456 from a cell phone. Call EH&S at (480) 965-1823.
If swallowed… DO NOT INDUCE VOMITING. Never give anything by mouth to an unconscious person. Drink 2-4 cups of milk or water. Seek immediate medical attention. Call 911 from a campus phone or (480) 965-3456 from a cell phone. Call EH&S at (480) 965-1823.
Special Storage & Handling Requirements
Storage

  • Ensure the container is tightly closed at all times.

  • Keep in a cool, dry, well-ventilated area away from incompatible materials and conditions.

  • Store away from heat, sparks, flame, and other sources of ignition.

  • Segregate from combustible materials and reducing agents.


Handling

  • The lab where the material is being handled has an approved / certified emergency eyewash and safety shower.

  • Ensure you are wearing the following minimum PPE: tightly fitting safety goggles, fire/flame resistant lab coat, full length pants, close-toe rubber or leather shoes, nitrile gloves.

  • Lab emergency contact information must be readily posted. Easy access to a cellular phone or land line is readily available.

  • Avoid contact with skin, eyes, and clothing.

  • Avoid inhalation and ingestion.

  • Avoid dust generation.

  • Provide adequate exhaust ventilation in places where dust is formed.

  • Keep away from heat, sparks, flame, and other sources of ignition.


Spill and Accident Procedure
Personal precautions

Avoid dust formation. Avoid breathing dust, vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Do not attempt clean-up without minimum PPE.


Environmental precautions

Prevent further leakage or spillage – if safe to do so. Do not allow product to enter drains.


Methods and materials for containment and clean-up

Consider material compatibility prior to clean-up. Verify spill kit is available. Sweep up spill and place in suitable, closed container for disposal. DO NOT use combustible materials such as paper towels to clean up spill.




  1. Immediately assess amount spilled, follow posted ASU Emergency Response Guide procedures for hazardous materials incidents.

  2. If a chemical exposure has occurred, a fellow lab worker shall call 9-1-1 and EH&S at (480) 965-1823.

  3. Don compatible gloves and other protective PPE if not already being worn.

  4. Secure / restrict access to the area of the spill to prevent spread of the chemical.

  5. Use the available spill kit to stop and contain the spill. Bag the collected material.

  6. Label and tag as hazardous waste and submit a pick-up request to EH&S using EHS Assistant.


Decontamination / Waste Disposal Procedure
Label waste

  • Attach a completed ASU Hazardous Waste tag to all waste containers as soon as the first drop of waste is added to the container.

Store waste

  • Store hazardous waste in closed containers, in secondary containment and in a designated storage location.

  • Double-bag dry waste using sealable transparent bags.

  • Waste must be under the control of the person generating and disposing of it.


Dispose of waste

  • Dispose of regularly generated chemical waste within 90 days.

  • Use EHS Assistant online hazardous waste pick-up request system.

  • Contact ASU EH&S at (480) 965-1823 with questions.
