Lesson 1: Risks at industrial sites

Industrial sites hold valuable goods, tools, fuel and metal, often spread over large yards. The main risks are:

  • Theft from outside: break-ins, stolen trailers or loads, and theft of metal such as copper wire.
  • Internal theft: losses that involve people who already have access, such as staff, drivers or contractors.
  • Fire: large amounts of stock, packaging and fuel can burn fast.
  • Safety hazards: forklifts, machines, chemicals and confined spaces.

You are also a worker on the site. Canadian health and safety law gives every worker three basic rights: the right to know about hazards, the right to participate in health and safety, and the right to refuse unsafe work. Follow the site's safety rules and wear the PPE its signs require, like everyone else.

Warning signs of internal theft

  • Goods stored near exits, fences or dumpsters for no clear reason
  • Loads leaving without matching paperwork, or with extra items
  • Doors propped or alarms turned off during a shift
  • People in areas where they do not normally work, especially after hours
  • Wear a hard hat
  • Wear safety footwear
  • Wear hearing protection
  • Wear high-visibility clothing

Lesson 2: The gate, shipping and receiving

The gate is where you control who and what comes in and goes out. Your post orders set the details. A typical gate routine:

StepWhat to do
Log inRecord the time, company, driver, truck and trailer numbers
VerifyCheck the appointment and paperwork, such as the bill of lading, against the post orders
Check the sealMake sure the seal is intact and its number matches the paperwork
DirectSend the driver to the right door or parking area
Log outRecord the time out and the new seal number on outbound loads

A seal is a numbered, one-time lock on a trailer door. If it is intact and matches the paperwork, the trailer has not been opened. If a seal is broken, missing or has the wrong number, do not open or accept the trailer. Record the details and report it.

When a vehicle has no appointment or the paperwork does not match, hold it at the gate and contact shipping or receiving. Sign in every visitor and contractor, explain the site safety rules and arrange an escort if required.

Lesson 3: Staying safe on the floor

Forklifts

Warning: forklift trucks operate here.
  • Walk only in designated pedestrian walkways.
  • Assume the operator cannot see you, and make eye contact before you step into a forklift's path.
  • Give forklifts plenty of room. They do not turn or stop like cars.
  • Wear high-visibility clothing where lift trucks work.

Lockout

Before workers repair or clean a machine, they shut off its energy and place a lock and tag on the switch or valve. Only the authorized person who placed the lock may remove it. Never touch, move or remove a lockout device, even if someone asks you to.

Confined spaces

Tanks, pits, silos and vaults can have deadly air. CCOHS reports that about 60% of confined space deaths are would-be rescuers. If someone collapses inside, call for emergency help and do not go in after them.

Lesson 4: Chemicals and fire protection

WHMIS is Canada's system for hazardous products at work. A supplier label shows the product name, the supplier, hazard pictograms, a signal word (Danger or Warning), hazard statements and precautionary statements. The safety data sheet (SDS) has 16 sections, including first aid, firefighting and spill steps, and must be readily available.

  • Flammable
  • Corrosive
  • Gas under pressure
  • Acute toxicity

If you find a spill or leak, keep people away, check the label or SDS from a safe distance, and call the emergency contact. Do not clean it up unless you are trained and equipped.

Fire protection checks

  • Fire exits and the paths to them are clear and doors are not locked shut.
  • Sprinkler control valves look open and are not tampered with. Report any that look closed right away.
  • Fire extinguishers are in place and not blocked.
  • The fire alarm panel shows no trouble signals, as your post orders describe.

If a fire starts

  1. Pull the nearest fire alarm and make sure 911 is called.
  2. Help people leave by the nearest safe exit and go to the assembly point.
  3. Meet the fire department and tell them about stored chemicals, fuel and anyone who may still be inside.

Lesson 5: Patrols, alarms and reports

At night, walk or drive the perimeter at changing times. Check fences, gates, lighting, doors and trailers in the yard. Thieves look for cut fences, dark corners and unlocked doors.

Vary your route and timing so no one can predict where you will be.

  1. A predictable loop: the same path at the same times. Anyone watching soon learns the gaps.
  2. An irregular route: a changing order that also covers the spaces between buildings.
  • Intrusion alarm: watch from a safe place and call police and the keyholder, as your post orders say. Do not go in alone.
  • Theft in progress: stay at a safe distance, call police and note descriptions, vehicles and plates. Do not confront or block anyone.
  • Injury: get first aid or call 911 as needed, then report it.
  • Lone work: check in at set times so someone can send help if you miss a call.
