- General SOPs can be found in the yellow SOP binders for each area that they might be applicable to, and should be signed in the area of use.
- Hard copies of all SOPs must be signed in the provided yellow binders, digital copies are provided for reference only.
- For more specific SOPs see the appropriate research area on the menu.
Standard Operating Procedures (SOPs)
With power tools there is common usage of eyes, face, hearing, feet, (hands when gloves do not pose an unsafe situation) and body. Ideal dress - long pants and closed footwear (CSA, Green Triangle safety shoes), no loose lab coats, long hair tied or tucked under hat, no dangling jewelry/watches or rings. All appropriate PPE must be readily accessible.
An effective lockout/tag out procedure must be utilized when changing cutting blades or where a job task could put operator at risk of an injury due to accidental startup or energy release.
Emergency stop buttons should be large and not broken. The best would be large mushroom head type when possible.
All tool and machine end power cord connection must be hardwired and in good condition â€“ not frayed or any internal wiring showing
Any tool(s) deemed unsafe or unfit for use must be immediately tagged as such and repaired or immediately removed from service.Â When unsafe tools are left unidentified on site, all personnel are exposed to great risk of being injured.Â If it is there they could still use it.Â
Step #1: Conduct Risk Assessment to Determine if Guards Are Required You first need to determine if any machinery in your workplace requires guards. The OHS laws generally require guards if workers using or working near that machinery could be exposed to the following hazards:
- Moving parts includes robotics
- Pinch points;
- Points of machinery at which material is cut, shaped, bored or formed;
- Surfaces with temperatures that may cause skin to freeze, burn or blister;
- Open flames;
- Energized electrical cables or components;
- Power transmission parts; couplers, keyways, set screws, shafts
- Debris, material or objects thrown from machinery;
- Material being fed into or removed from process machinery;
- Machinery or equipment that may be hazardous due to its operation; or
- Any other hazard posed by the machinery.
