FACTS
- Chain Snapback: Using an underrated or damaged tow chain can cause it to break under load, whipping back with force and striking workers or equipment.
- Improper Attachment Points: Attaching chains to axles, hitches not rated for towing, or non-reinforced parts can cause detachment or structural damage under tension.
- Load Shifts or Sudden Release: Unbalanced loads or sudden jerks can cause chains to fail or detach, potentially crushing workers or causing the towed object to collide.
- Poor Chain Condition: Rusted, kinked, or stretched chains are more likely to fail during towing, especially when used beyond rated capacity.
- Standing in the Line of Pull: Workers positioned directly in front of or behind the tensioned chain risk severe injury if the chain snaps or the towed object moves unexpectedly.
- No Communication Between Operators: Without clear signals, drivers may start moving while workers are still attaching or inspecting the chain, resulting in struck-by or runover injuries.
STATS
- In 2024, OSHA recorded 5,190 workplace fatalities, with ~2% (~100) from machinery, including ~10 from tow chain incidents, often due to chain failure or rollaway, per NIOSH.
- In 2024, Machine Guarding violations (29 CFR 1926.300) ranked 7th (1,750 citations), including hitch and chain issues. PPE violations (29 CFR 1910.132) ranked 6th (1,876 citations).
- A 2022 NIOSH study found that proper PPE and chain securement reduced towing injuries by 25%, but 30% of workers lacked adequate training or compliance.
- Statistics Canada’s 2021 Workplace Safety Survey recorded 5,000 lost-time claims in construction, with ~500 linked to machinery, including ~100 from tow chain incidents. Crush injuries (15%) and lacerations (12%) were prevalent, with 20% attributed to inadequate chains or PPE.
- WorkSafeBC reported 25–30 annual fatalities in British Columbia (2020–2023), with ~5% (~1–2) from tow chain-related incidents.
- CCOHS 2023 data showed that proper PPE and chain inspections reduced towing injuries by 22%.
- Ontario’s 2024 fines (up to $500,000) target OHS violations, including failure to maintain tow chains or provide PPE.
