Study Notes
Laboratory Hazards and Controls
- This module is about laboratory hazards and controls.
- Upon completion, students should understand the elements of an effective laboratory safety program and the causes of laboratory incidents at their school.
- Students should be able to apply energy source and hazard recognition to various lab situations.
- They should also apply hierarchy of controls in hazardous lab settings.
- Students should be able to identify missing elements in their school's laboratory safety program.
- The module is not meant to replace university/college safety orientation training but rather apply hazard and risk controls to a lab environment.
Topic 1: Putting Safety First
- Labs are often more hazardous than average workplaces.
- Students need to be aware of potential hazards and risks in their school's labs.
- Students should be trained in laboratory safety, and this training should include WHMIS (Workplace Hazardous Materials Information System) training if hazardous materials are used.
- Each province has regulations requiring WHMIS training in workplaces.
- Specific incidents in academic labs highlight the importance of safety training and clear safety protocols.
Topic 2: Identifying and Understanding Lab Hazards
- A hazard is a source of potential harm, and a risk is the likelihood and severity of harm from that hazard.
- Hazards are tied to energy sources, mechanical, chemical, electrical, or thermal energy, etc.
- The hierarchy of controls is a method of risk management in order of descending effectiveness.
- Elimination (remove the hazard altogether)
- Inherent Safety (design the lab or process to reduce inherent hazards)
- Engineering Controls (e.g., enclosed systems to prevent exposure to substances)
- Administrative Controls (rules, training, and procedures)
- Personal Protective Equipment (PPE, which is lower on the hierarchy of controls)
- Approaches to hazard identification can be based on a person's experience and/or identifying energy sources.
- Gravity, mechanical, chemical, and radiation energy are possible hazards.
Topic 3: The Elements of an Effective Laboratory Health and Safety Management Program
- A solid program is essential to keep labs safe.
- Ten essential elements to an effective lab safety program include:
- Leadership
- Hazard Identification
- Planned Inspections
- PPE
- Job safety analysis and safe operating procedures
- Safe handling of materials
- Lab management
- Training and records
- Field level risk assessment (FLRA)
- Reporting and correction of incidents
- Training for students and lab personnel is a key element.
- Safety information must be consistent with any regulations for material safety data sheets (MSDS) and Workplace Hazardous Materials Information Systems (WHMIS).
- Lab management includes controlling access to labs and handling emergencies.
- FLRA should be completed before any lab task, whether involving one student or multiple students.
MSDS (Material Safety Data Sheet): A document that provides information on the potential hazards associated with a particular chemical and how to handle, store, and dispose of it safely. 56 -
WHMIS (Workplace Hazardous Materials Information System): A Canadian system of legislated standards that provides information on hazardous materials in the workplace. It requires employers to label hazardous materials and provide training on their safe handling and use. 66
Used methods in Lab: PPE and Administrative controls
