SOP ID	SOP-COSTCO-002
Version	1.0 (overlay of SOP-GEN-006 v1.0)
Owner	Site Manager
Review	On site change / annual / post-incident

🛑 The general non-negotiables still apply

LOTO, electrical approach limits, fall protection, hot-work permits, stop-work right (OHSR s.3.12). This page adds Costco specifics — it does not replace them.

1 Warehouse / Retail-Floor Hazards

Hazard	Control at Costco	Anchor
Forklift / pedestrian conflict	Designated walkways; hi-vis (Class 1+ in equipment zones, Class 3 at night); eye-contact + acknowledgment before entering a zone; clear forklifts before EWP moves	OHSR s.16.6, 8.24
Dust/debris near food areas	Physical containment (barriers, poly sheeting) before work near food court/deli/bakery; clean-up verified before removing barrier	Part 4 + food bylaws
Refrigeration / freezer	Confirm refrigerant type (CO₂ displacement / ammonia risk in older systems) & ventilation before entry; cold-exposure limits; buddy + rescue plan	Part 5 / 7; WSBC ammonia guide
Slip on sales floor	Immediate spill response; cords overhead/covered; signage even for light condensation	Part 4
Elevated work over floor	EWP harness rules; off-hours only on sales floor; coordinate with facilities	Part 13

2 Electrical & HVAC Work

Low-voltage (<750 V): fully disconnect + lock out before work (OHSR Part 19 s.19.10); personal lock per worker (Part 10)
Unqualified workers stay ≥ 3 m from exposed energized equipment 750 V–75 kV (Table 19-1A)
Arc-flash + shock training before work near energized equipment; arc-flash PPE for any permitted live work
Electrical installations: BC Electrical Code / Technical Safety BC permit (TSBC is separate from WorkSafeBC)
Breaker-panel changeouts sized for the new load per BC Electrical Code

3 Hot Work at a Big-Box Facility

🔥 Permit + facility authorization

Hot work needs the standard permit (combustibles cleared 10 m, fire watch during + ≥30 min after) and facility-level authorization. Sprinkler-impairment notification typically routes through Costco property management / operations — not the contractor directly to the fire department. Confirm the route before isolating any system. (BC Fire Code Div. B s.5.2) TODO(confirm) facility process

4 After-Hours Specifics

Reduced staffing → establish check-in schedule (every 30–60 min) with overnight security; working-alone procedure if anyone is separated (OHSR s.4.20.1–4.23)
Briefed on alarm codes/zones + notify monitoring before sensor-triggering work; false-alarm protocol confirmed
Documented, signed after-hours work authorization on site
ANSI/CSA Class 3 hi-vis for all night work where equipment moves
Restricted zones (server, pharmacy, receiving with inventory) physically confirmed before work

5 Prime Contractor & Coordination

If Liquid Rock works alongside other employers' workers at the same time, confirm the designated Prime Contractor for the site and the coordination plan (WCA s.118–120). See Role Definitions §4.
