Brief description of proposed chemical work: To make brine solutions of corrosion experiments
Section 1: Brief Safety Overview:
●The Principal Investigator is responsible for training employees using the material on site. The training should include a discussion of the known and potential hazards; an explanation of the relevant policies, techniques and procedures including the proper use of personal protective equipment, emergency/spill procedures and containment equipment (engineering controls).
●Limit access to authorized users.
●Minimize the possibility of inadvertent ingestion, inhalation and direct skin or eye contact with the substance.
●Chemical has been entered in the Chemical Inventory (EHS Assistant)
●Require annual training.
Section 2: Research Laboratory Procedures
- Handling Instructions
Avoid all personal contact, including inhalation.
Wear protective clothing when risk of exposure occurs.
Use in a well-ventilated area.
Prevent concentration in hollows and sumps.
- Storage:
Store in original containers.
Keep containers securely sealed.
Store in a cool, dry area protected from environmental extremes.
Store away from incompatible materials and foodstuff containers.
Location – Engineering controls
Ventilation (example: Fume Hood, Canopy Hoods, etc):
Designated area (specify):
Bio-Safety Cabinet
PPE required:
Skin/Body Protection (example: Lab Coat)
Eye protection
Face shield
Respirator (example: N95):
Hand protection (example: Nitrile gloves):
- Cleanup/Decontamination procedures for work area after use:
- Disposal Procedures
This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use.
DO NOT allow wash water from cleaning or process equipment to enter drains.
It may be necessary to collect all wash water for treatment before disposal.
In all cases disposal to sewer may be subject to local laws and regulations and these should be considered first.
Where in doubt contact the responsible authority.
Recycle wherever possible or consult manufacturer for recycling options.
Consult State Land Waste Management Authority for disposal.
Bury residue in an authorised landfill.
Recycle containers if possible, or dispose of in an authorised landfill.

- Toxicological Effects
Acute Effects/ Precautionary Safety Measures:
No acute effects
Chronic Effects/ Precautionary Safety Measures:
Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems.
Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems.
Long term exposure to high dust concentrations may cause changes in lung function (i.e. pneumoconiosis) caused by particles less than 0.5 micron penetrating and remaining in the lung. A prime symptom is breathlessness. Lung shadows show on X-ray.
- Occupational Exposure Response and First Aid Measures

Eyes:
Inhalation:
Ingestion:
- Emergency Procedure for Chemical Spills and Accidental Releases
Minor spills:
Clean up all spills immediately.
Avoid breathing dust and contact with skin and eyes.
Wear protective clothing, gloves, safety glasses and dust respirator.
Use dry clean up procedures and avoid generating dust.
Major spills:
Moderate hazard.
CAUTION: Advise personnel in area.
Alert Emergency Services and tell them location and nature of hazard.
Control personal contact by wearing protective clothing.
This Standard Operating Procedure must be placed in the Chemical Hygiene Plan and the SDS must be accessible. Also, all laboratory personnel must be familiar with safe handling practices (i.e., training with documentation of training) when working with these chemicals. This must be incorporated into the comprehensive chemical hygiene plan of the laboratory. If you have any questions regarding a comprehensive mandatory laboratory chemical hygiene plan please contact your Representative at Environmental Health and Safety (292-1284).For any other questions or concerns, please contact:
