Confined Space Regulations 263(1) Where an employee is about to enter a confined space, an employer shall appoint a competent person to verify by tests that: 263(1)(a)the concentration of airborne chemical agents or airborne dust in the confined space is not hazardous…, 263(1)(b)the concentration of an airborne chemical or mixture of chemical agents or airborne dust in the confined space does not exceed 50% of its lower explosive limit,
7
Confined Space Regulations 263(1)(c)the level of physical agents in the confined space is not hazardous… 263(1)(d)the percentage of oxygen in the atmosphere in the confined space is not less than 19.5% by volume and not more than 23% in volume
8
Confined Space Regulations 263(1)(e) the concentration, level or percentage referred to in paragraphs (a) to (d) is able to be maintained during the period of proposed occupancy of the confined space by the employee 263(1)(h)all electrical equipment and machines have been locked out, with the machines being put in a zero energy state.

Confined Spaces - Hazardous
10
Employer’s Responsibilities
Instruct and train workers Purge when necessary Provide PPE and emergency equipment To ensure the worker has read, dated and signed the report
Appoint a competent tester
11
Competent Person According to the 91 191 I(2) regulation, ‘Competent’ means I.
II.
Qualified: ‘knowledge, training, and experience, to do assigned work in a manner that will ensure health and safety’ Knowledgeable: about the related act and regulations III. Knowledgeable: about the related potential for danger
12
Competent Person
Do the tests (oxygen, flammability, toxicity, etc.)
Be trained in the procedures Be in attendance outside Ensure constant communication Have a standard-level first aid and CPR
13
Competent Person
Ensure continuous monitoring Set out procedures Set out the results (tests) Identify the proper PPE and emergency equipment
Calibrate instruments
14
Employee’s Responsibilities
Competent person follows procedures Install warning signs if there’s a traffic hazard Follow procedures Use PPE and emergency equipment Read and sign the report of the competent tester
15
Written Report 1. Sets out the Results (tests) Evaluation (hazards) 2. Sets out procedures to be followed 3. Identifies PPE 4. Sets out emergency procedures
16
Written Report 5. Identifies equipment and rescuer 6. Kept at the worksite 7. Kept for a period of 2 years 8. Available to an officer
17
Three People Are Needed… 1. Entrant: Read, date and sign report 2. Person outside the entrance (standby): Competent 3. Back-up: Near Vicinity
18
Safe Work Procedures
Preplan the job
Prepare and check equipment
Ensure traffic control
Test before opening and record
Follow correct opening procedures
19
Safe Work Procedures
Record results of re-test
Ventilate and purge if required
Set up an escape and rescue plan
Ensure continuous monitoring if necessary
20
Protective Equipment Employer shall:
Provide PPE in good condition
Inspect regularly
Ensure employee training
21
Protective Equipment Employee shall:
Wear and use
Use properly
Inspect and test
Report problems
22
Equipment
In wet conditions, equipment should be:
1. Battery operated 2. Double insulated 3. Bonded or grounded
*Be aware of other hazardous conditions
Example: Chemicals, moving equipment, etc.
23
Oxygen Less than 19.5%:
Use appropriate RPE Reserve 5 minutes More than 23%:
No flammable, combustible or reactive material
24
Unsafe Conditions Safety Hazards Atmospheric Hazards Unsafe Actions
25
Hazard Recognition
Solids (entrap)
Liquids (drown)
Atmospheric hazards
Machines or equipment (trap, squeeze or crush)
Bulk materials (shift or collapse)
26
Hazard Recognition
Electrical shock
Rescue equipment (non functional)
Size of entrance (too small)
Rusted ladder
27
Hazard Recognition
Traffic Hazards Temperatures Visibility
Slippery Work Surfaces Lack of Education & Training Lack of enforcement
*NOTE: Never put yourself in a position where you need to be rescued
