Study Notes

Chemical Safety

Learning Outcomes: Proper usage of personal protective equipment (PPE) and procedures.
Learning Objectives: Understanding PPE, its use, and minimizing workplace risks.
Definition of Terms:
- Chemical: Any element, compound, or mixture.
- Safety: Freedom from harm or injury.
- Hazard: A potential source of risk to safety or health.
- Chemical Safety: Safe handling of chemicals - avoiding harm.
- Chemical Hazards: Chemicals that pose risk.
- PPE (Personal Protective Equipment): Equipment to protect against workplace hazards.
Importance of Chemical Safety:
- Protects people: Prevents injuries, illnesses, and deaths.
- Protects property: Prevents damage.
- Protects a company's reputation: Builds trust.
- Reduces costs: Fewer accidents, less medical expenses.
- Improves employee morale: Safer environment boosts performance.
- Meets regulations: Compliance through adhering to rules.
- Demonstrates sustainability: Reduces chemical waste and safely uses materials.
Chemical Safety in the Workplace:
- Training: Providing chemical safety training.
- PPE Access: Ensuring appropriate PPE is available.
- Handling Procedures: Implementing proper procedures.
- Waste Minimization: Reducing chemical waste through proper storage and disposal.
General PPE Requirements (Laboratory/Workplaces):
- Long sleeves, buttoned lab coat, safety glasses, fully enclosed shoes are mandatory.
- Tying back hair and wearing a hairnet, gloves and safety glasses in many situations.
- Hazard assessment needed to determine most effective controls to minimize hazards.
- If other methods not feasible, PPE must be used appropriately.
PPE is only effective if used correctly.
Potential Hazards (Laboratory):
- Splashes from chemicals
- Harmful gases or vapors
- Harmful dusts
- Impacts from broken equipment (glass)
- Cryogens
- Irritants/Tear gas
- Biological materials
- Extreme temperatures
- Noise
Eye and Face Protection:
- Safety Glasses: Scratch-resistant, lightweight, anti-fog, wrap-around.
- Safety Goggles: For chemical splashes, cover eyes and surrounding area.
- Laser Safety Goggles: Necessary for laser hazards.
- Face Shields: For splashes and airborne particles, fit snugly to the head.
Foot Protection:
- Shoes should cover whole foot, leather is highly resistant to chemicals, materials.
- Thongs, sandals, and open-toe shoes are not permitted.
Hand Protection (Gloves):
- Various types for different hazards (chemical, solvent, corrosive).
- Gloves should be selected based on the chemical/hazard and duration of exposure. Materials vary.
- Check for leaks, cuts and tears in gloves before using them.
Clothing:
- Long-sleeved, fully buttoned lab coats.
- Remove lab coat on leaving lab, clean it regularly according to protocol.
Respiratory Protection:
- Disposable Masks: For dusts (silica).
- Half-Face Respirators: For gases, vapors, and particulate matter.
Hearing Protection:
- Exposure to excessive noise requires the use of earplugs or earmuffs.
- The intensity and duration of the sound influence whether or not protection is required.

Chemical Handling

Storage: Store chemicals in a cool, dry area, and out of reach of children and animals.
Labeling: Use clear labels (description, signal words, pictograms, hazard statements)
Reading Labels: Always read and follow chemical labels.
PPE Use: Always wear appropriate PPE.
Handwashing: Wash hands after handling chemicals.
Spills: Know what to do and have a plan in case of spills.
Disposal: Dispose of chemical safely - not into drains, toilets, or other improper locations.
Safety Data Sheets (SDS): Essential for proper handling and use of chemicals.
Training: Staff need to understand risks and proper handling of chemicals.
