Work Practices and Safety Procedures
Module Introduction
This first chapter forms the foundation of your preparation for the Red Seal exam for the motorcycle technician trade. Work practices and safety procedures are not simply a preamble: they represent approximately 10 to 15% of the questions on the interprovincial exam, and they condition your ability to correctly answer questions from other blocks (maintenance, repair, diagnostics). A technician who does not master safety rules is a danger to themselves, their colleagues, and the public. This chapter covers all the knowledge required by the National Occupational Analysis, with references to applicable Canadian standards.
1. Legal and Professional Responsibilities of the Technician
1.1 General Obligations
As a certified motorcycle technician, you are bound by legal and professional obligations:
Duty of competence: you must only undertake work for which you have the required training and experience.
Duty to inform: you must inform the client of any defect or dangerous condition discovered, even if this defect is not part of the initial mandate.
Duty of diligence: you must apply manufacturer procedures and current standards, without taking shortcuts.
1.2 Reference Canadian Standards
The table below presents the main standards to which the motorcycle technician must refer:
| Standard | Full Designation | Primary Application |
|---|
| **CSA B149.1** | Natural Gas and Propane Installation Code | LPG/CNG fuel systems (conversions) |
| **CSA B149.2** | Propane Storage and Handling Code | Propane tanks for motorcycles |
| **Canadian Electrical Code, Part I (CE Code)** | Canadian Electrical Code, Part I | 12 V electrical systems, battery chargers, welding |
| **CSA W47.1** | Certification of Welding Companies | Welding on frames and supports |
| **CSA W59** | Welded Steel Construction | Frame repair (if applicable) |
| **CAN/ULC-S601 Standard** | Standard for Gasoline Tanks | Fuel tank integrity |
> Exam Point: The Canadian Electrical Code, Part I (CE Code) applies to electrical installations in workshops, including lighting circuits, receptacles, and battery charging equipment. Rule 8-200 of the CE Code deals with circuit load calculations — you must know that a 15 A, 120 V circuit must not be loaded to more than 80% continuously (12 A).
1.3 Documentation and Safety Data Sheets (SDS)
The Hazardous Products Act and WHMIS 2015 (Workplace Hazardous Materials Information System) require that:
All SDS be available and accessible in the workshop.
Containers be labelled in accordance with WHMIS (supplier or workplace label).
The technician know how to interpret hazard pictograms.
The 9 WHMIS pictograms you must know:
| Pictogram | Meaning | Workshop Example |
|---|
| Flame | Flammable material | Gasoline, thinner |
| Flame over circle | Oxidizer | Peroxide, oxygen |
| Gas cylinder | Gas under pressure | Nitrogen, acetylene |
| Corrosion | Corrosive material | Battery acid, alkaline degreaser |
| Skull and crossbones | Acute toxicity | Antifreeze (ethylene glycol) |
| Exclamation mark | Health hazard | Solvents, cleaners |
| Silhouette | Health hazard (chronic effects) | Asbestos (brake pads) |
| Environment | Environmental hazard | Used oil, coolant |
| Head over chest | Biohazard | Mould (rare in workshop) |
2. Personal Protective Equipment (PPE)
2.1 Mandatory PPE in the Motorcycle Workshop
Wearing PPE is not optional. The employer must provide PPE, and the technician must wear it. The following PPE is required:
Safety glasses with side protection (mandatory at all times in the work area).
Hearing protection (plugs or earmuffs) when noise levels exceed 85 dB(A) — this is the case during engine testing, grinding, and sandblasting.
Safety footwear with steel toe (CSA Z195 standard).
Hydrocarbon-resistant work gloves (nitrile or neoprene) for handling oils and solvents.
Leather welding gloves for any welding or grinding operation.
Flame-resistant apron or work clothing for welding.
2.2 PPE Specific to the Operation
| Operation | Required PPE | Justification |
|---|
| Battery charging | Safety glasses, nitrile gloves, apron | Risk of sulfuric acid splashing |
| Arc welding | Welding helmet (shade 10-13), leather gloves, flame-resistant clothing | UV radiation, metal spatter |
| Grinding | Safety glasses, face shield, gloves, hearing protection | Flying debris, noise |
| Paint spraying | Respirator with cartridge (organic vapours), sealed safety glasses | Inhalation of solvents and isocyanates |
| Road test | Certified helmet (DOT or SNELL standard), gloves, boots, jacket | Protection in case of a fall |
> Exam Trap: Wearing medical latex gloves is not acceptable for handling gasoline or solvents — latex dissolves on contact with hydrocarbons. Use nitrile or neoprene.
3. Fire Safety and Hazardous Materials Management
3.1 Fire Classification and Extinguishers
NFPA 10 (adopted in Canada) classifies fires into five categories. For the motorcycle workshop, classes B (flammable liquids) and C (electrical equipment) are the most relevant.
| Fire Class | Type of Fuel | Appropriate Extinguisher |
|---|
| A | Solid materials (wood, paper) | Water, ABC |
| B | Flammable liquids (gasoline, oil) | CO₂, ABC powder, foam |
| C | Electrical equipment | CO₂, ABC powder |
| D | Combustible metals (magnesium, aluminum) | Special Class D powder |
| K | Cooking oils | Foam, wet chemical |
Golden Rule: Never use water on a Class B or C fire. Water spreads flammable liquids and conducts electricity.
3.2 Storage of Flammable Liquids
The National Fire Code of Canada requires:
Flammable liquids (gasoline, solvents) must be stored in certified safety cabinets, with a maximum capacity of 250 L per cabinet.
Portable containers must be metal or certified plastic, with a spring-loaded cap and a flame arrestor screen.
Bulk storage (200 L drums) must be in a separate, ventilated room with a containment sill.
Gasoline must never be stored in glass or non-certified plastic containers.
3.3 Hazardous Waste Management
The following wastes are considered hazardous and must be disposed of according to provincial and federal regulations (Canadian Environmental Protection Act):
Used engine oil (separate collection, never into sewers).
Coolant (ethylene glycol-based antifreeze — toxic).
Brake fluid (glycol ether — toxic and flammable).
Battery acid (neutralize with baking soda before disposal).
Used solvents (distillation or collection by an authorized carrier).
Used tires (mandatory recycling in most provinces).
> Exam Point: DOT 3, DOT 4, and DOT 5.1 brake fluid is glycol ether-based and is hygroscopic (absorbs moisture). DOT 5 is silicone-based and is not hygroscopic. Never mix DOT 5 with DOT 3/4/5.1 — complete incompatibility.
4. Electrical Safety in the Workshop
4.1 Fundamental Principles
The Canadian Electrical Code, Part I (CE Code) governs electrical installations in industrial and commercial establishments, including repair workshops. Key rules:
Rule 8-200: Circuit load calculation. A branch circuit must not be loaded to more than 80% of its rated capacity for continuous loads.
Rule 10-204: Equipment grounding. All electrical equipment must be grounded.
Rule 12-100: Conductors — wires must be protected against mechanical damage.
Rule 26-700: Receptacles — receptacles in workshops must be lockable type or protected by a ground fault circuit interrupter (GFCI) when within 1.5 m of a water source.
4.2 Battery Charging Safety
Charging a motorcycle battery (typically 12 V, 5-20 Ah) presents specific risks:
Hydrogen gas release: Charging produces hydrogen gas, explosive in air at concentrations of 4 to 75%. Ventilate the charging area.
Sparks: Disconnect the battery before working on the electrical circuit. Always disconnect the negative terminal first, and reconnect it last.
Sulfuric acid: The battery contains sulfuric acid (H₂SO₄) at approximately 35%. In case of contact: rinse thoroughly with water for 15 minutes, seek medical attention.
Safe charging procedure:
70.Check electrolyte level (conventional batteries) — add distilled water if necessary.
71.Connect the charger: positive (+) charger lead to positive (+) battery terminal, then negative (−) lead to negative (−) terminal.
72.Set the charger to the recommended voltage and current (generally 1/10 of the Ah capacity for slow charging).
73.Never charge a frozen or cracked battery.
74.Disconnect the charger before disconnecting the battery cables.
4.3 Welding and Electrical Safety
Arc welding (SMAW, GMAW/MIG, TIG) presents electrical hazards:
The open-circuit voltage of a welding machine can reach 80-100 V — enough to cause a fatal shock in damp conditions.
Never weld on a motorcycle with the battery connected — risk of electronic damage (ECU, regulator, etc.).
Always disconnect the battery and disconnect the ECU before any welding.
The welding current return path must never pass through bearings or electronic components.
5. Lifting and Handling
5.1 Safe Lifting Principles
Manual handling is a major cause of injury. Basic principles:
Base position: feet shoulder-width apart, back straight, knees bent, load close to the body.
Lifting limit: for a healthy adult male, the recommended limit is 25 kg for occasional lifting, 15 kg for repetitive lifting. A complete motorcycle weighs between 120 and 350 kg — never attempt to lift one alone.
Technique for lifting a fallen motorcycle: back straight, knees bent, grasp the handlebar and frame, push with the legs, never with the back.
5.2 Workshop Lifting Equipment
| Equipment | Typical Capacity | Use |
|---|
| Hydraulic lift table | 450-900 kg | Lifting the complete motorcycle |
| Engine hoist | 200-500 kg | Engine removal and installation |
| Electric chain hoist | 500-2000 kg | Lifting heavy engines |
| Centre stand | Model-dependent | Holding the rear wheel raised |
| Front wheel stand | 50-150 kg | Holding the front wheel raised |
Lift table operating procedure:
91.Check the table's rated capacity (never exceed it).
92.Position the motorcycle in the centre of the table, side stand up.
93.Secure the motorcycle with straps (front and rear) before lifting.
94.Lift to working height, then mechanically lock the table (never rely solely on the hydraulic cylinder).
95.Before lowering, check that no obstacles are under the table.
> Exam Trap: The side stand is not a support device for working under the motorcycle. It can fold up, or the ground can give way. Always use a lift table or a centre stand with support.
6. Road Safety and Road Testing
6.1 Motorcycle Preparation for Road Testing
Before any road test, the technician must perform a pre-test inspection:
Brakes: operation, fluid level, pad wear.
Tires: pressure (cold), tread depth (legal minimum: 1.5 mm in Canada for motorcycles), general condition.
Lighting: headlight (low and high beam), turn signals, brake light, tail light.
Steering: free play, steering head bearings, alignment.
Suspension: leaks, operation.
Fluid levels: engine oil, coolant, brake fluid.
Fuel: sufficient level for the test.
6.2 Driving Rules for the Road Test
The technician must hold a valid driver's licence of the appropriate class (Class 6 for motorcycles in Canada).
Wearing a certified helmet is mandatory in all provinces and territories.
The road test must be conducted on a predefined route, under normal traffic conditions.
During the test, monitor: engine temperature, pressures, abnormal noises, vibrations, steering and brake behaviour.
In case of a dangerous anomaly (brake failure, unstable steering), stop immediately and return the motorcycle to the workshop.
6.3 Brake Testing
The on-road brake test must verify:
Front brake: the motorcycle must stop in a stable manner, without excessive nose dive or lateral deviation.
Rear brake: must not lock the wheel (except ABS in operation).
Stopping distance: at 50 km/h on dry pavement, the stopping distance must not exceed approximately 15 m for a motorcycle in good condition (with an experienced rider).
7. Chemical Safety and Ventilation
7.1 Exposure to Hazardous Substances
The motorcycle technician is exposed to many hazardous substances. Occupational exposure limits (OELs) are defined by the Canada Occupational Health and Safety Regulations (federal) and provincial regulations. Key values:
| Substance | OEL (8-hour time-weighted average) | Primary Risk |
|---|
| Carbon monoxide (CO) | 25 ppm | Asphyxiation, acute poisoning |
| Carbon dioxide (CO₂) | 5000 ppm | Asphyxiation |
| Benzene (in gasoline) | 0.5 ppm | Leukemia, cancer |
| Toluene (in solvents) | 20 ppm | Neurotoxicity |
| Lead (batteries, solders) | 0.05 mg/m³ | Neurotoxicity, lead poisoning |
| Isocyanates (paints) | 0.005 ppm | Occupational asthma |
| Asbestos (older brake pads) | 0.1 fibre/cm³ | Mesothelioma, asbestosis |
7.2 Workshop Ventilation
General ventilation must provide an air exchange rate of at least 4 volumes/hour in a repair workshop.
Battery charging and welding areas require local exhaust ventilation (hood or extraction arm).
Carbon monoxide (CO) produced by running engines is a deadly hazard. Engine testing in the workshop must be done with an exhaust extraction system connected to the exhaust pipe.
A CO detector must be installed in the workshop, with an alarm.
> Exam Point: CO is odourless, colourless, and tasteless. Symptoms of poisoning (headache, nausea, confusion) appear at 100 ppm. At 400 ppm, poisoning is severe. At 1200 ppm, death can occur in less than one hour.
8. Safety Procedures Specific to Fuel Systems
8.1 Handling Gasoline
Gasoline is an extremely flammable liquid (flash point: −43 °C) and explosive (flammability limits: 1.4 to 7.6% by volume in air). Safety rules:
Work in a well-ventilated area, away from any ignition source.
Disconnect the battery before any work on the fuel system.
Depressurize the system before disconnecting lines (remove the fuel pump fuse and run the engine until it stops, or use the manufacturer's procedure).
Use approved containers to collect fuel.
Never smoke, never use a cell phone (spark risk) in the work area.
Clean up any spill immediately with an absorbent product (not sawdust — it is flammable).
8.2 LPG/CNG Systems (Conversions)
If the motorcycle is equipped with a propane (LPG) or natural gas (CNG) system, standards CSA B149.1 and CSA B149.2 apply:
The tank must be certified and bear the certification mark.
Lines must be made of compatible material and protected against mechanical damage.
Fittings must be leak-checked with a soap solution (never with a flame).
The tank test pressure is generally 1.5 times the service pressure.
The technician must hold specific certification to work on LPG/CNG systems (training per CSA B149.1).
9. Waste Management and Environmental Protection
9.1 Environmental Regulations
The Canadian Environmental Protection Act (CEPA) and provincial regulations require:
Prohibition on discharging used oils, coolants, or solvents into sewers, waterways, or the ground.
Obligation to store hazardous waste in sealed, labelled, closed containers.
Obligation to maintain a waste log (quantities, dates, authorized carrier).
Mandatory recycling of tires, batteries, and ferrous and non-ferrous metals.
9.2 Refrigerants and Air Conditioning
Some high-end motorcycles are equipped with air conditioning systems (rare, but present on touring bikes). Refrigerants (R-134a, R-1234yf) are regulated greenhouse gases:
Refrigerant recovery is mandatory (Ozone-depleting Substances Regulations).
The technician must be certified to handle refrigerants (training per CSA standard).
Never vent a refrigerant to the atmosphere.
10. First Aid and Emergency Situations
10.1 First Aid Kit
The workshop must have a complete first aid kit, compliant with provincial requirements. It must contain at minimum:
Bandages, sterile dressings, adhesive tape.
Antiseptic solution (chlorhexidine or iodine).
Disposable nitrile gloves.
Sterile eye wash (for chemical splashes).
Emergency blanket.
Rescue mask (mouth-to-mouth).
10.2 Specific Emergency Procedures
| Situation | Immediate Action |
|---|
| Acid splash in eyes | Rinse with water (or saline solution) for 15 minutes, eyelids open. Seek medical attention. |
| Chemical burn (skin) | Remove contaminated clothing, rinse with running water for 15 minutes. |
| Thermal burn | Cool with lukewarm water (15-20 °C) for 15-20 minutes. Do not pop blisters. |
| CO poisoning | Move victim to fresh air, call emergency services, perform CPR if necessary. |
| Fire | Raise the alarm, evacuate, use the appropriate extinguisher (Class B or C). Never fight a significant fire. |
| Electric shock | Cut the power before touching the victim. Call emergency services. CPR if necessary. |
10.3 CPR and Defibrillator
The technician must be trained in CPR (cardiopulmonary resuscitation) and the use of an AED (automated external defibrillator).
CPR ratio for an adult: 30 compressions to 2 breaths, at a rate of 100-120 compressions/minute, with a depth of 5-6 cm.
The AED must be used as soon as possible — every minute of delay reduces survival chances by 7 to 10%.
Summary
This chapter has covered the essential elements of work practices and safety procedures for the motorcycle technician. Key points to remember:
179.Legal responsibilities: duty of competence, duty to inform, and duty of diligence. Knowledge of Canadian standards (CSA B149.1, CE Code Part I, WHMIS 2015).
180.PPE: mandatory wearing, adapted to each operation. Nitrile for hydrocarbons, never latex.
181.Fire safety: fire classification (A, B, C, D, K), appropriate extinguishers, storage of flammable liquids in certified cabinets.
182.Electrical safety: Rule 8-200 of the CE Code (max 80% load), disconnect the negative terminal first, ventilation during battery charging (explosive hydrogen).
183.Lifting: limits of 25 kg (occasional) and 15 kg (repetitive), mechanical locking of lift tables.
184.Road tests: complete pre-test inspection, valid driver's licence, certified helmet mandatory.
185.Chemical safety: OELs for CO (25 ppm), benzene (0.5 ppm), ventilation of 4 volumes/hour, exhaust extraction.
186.Fuel systems: depressurize before working, gasoline flash point at −43 °C.
187.Environment: hazardous waste management per CEPA, mandatory recycling.
188.Emergencies: CPR (30:2, 100-120 compressions/min), AED, 15-minute eye rinse for chemical splashes.
Traps to Avoid
Here are the most frequent errors made by Red Seal exam candidates on this subject:
192.Confusing fire classes: A gasoline fire is Class B, not Class A. Never use water on a Class B or C fire.
193.Forgetting the battery disconnection order: Always disconnect the negative terminal first and reconnect it last. The reverse can cause a short circuit if the tool touches the frame.
194.Neglecting the hydrogen risk during charging: Hydrogen is explosive at 4% in air. One spark is enough. Ventilate imperatively.
195.Confusing DOT 5 and DOT 5.1: DOT 5 is silicone-based (non-hygroscopic), DOT 5.1 is glycol-based (hygroscopic). They are never compatible with each other, nor with DOT 3/4.
196.Using latex for hydrocarbons: Latex dissolves. Use nitrile or neoprene.
197.Overloading an electrical circuit: Rule 8-200 of the CE Code limits continuous load to 80% of rated capacity. A 15 A circuit must not exceed 12 A continuously.
198.Welding with the battery connected: Welding current can destroy the ECU, regulator, and other electronic components. Always disconnect the battery and disconnect the ECU.
199.Relying solely on the hydraulic cylinder: A lift table must be mechanically locked before working under the motorcycle. The cylinder can fail.
200.Ignoring CO exposure limits: CO is odourless and deadly. The OEL is 25 ppm over 8 hours. Exhaust extraction is mandatory during engine testing in the workshop.
201.Not depressurizing the fuel system: Before disconnecting a fuel line, the system must be depressurized (fuel pump fuse removed, engine run until it stops). Pressurized gasoline can cause dangerous spraying.
202.Confusing lifting limits: The 25 kg limit is for occasional lifting, 15 kg for repetitive lifting. A complete motorcycle (120-350 kg) is never lifted alone.
203.Forgetting the pre-road-test inspection: Road testing without prior inspection of brakes, tires, and lighting is a serious fault. The minimum tread depth is 1.5 mm in Canada.
204.Neglecting WHMIS: SDS must be accessible. Pictograms must be known. The "flame" pictogram indicates a flammable product, not simply a hot product.
205.Using sawdust to absorb gasoline: Sawdust is flammable. Use an inert absorbent (clay, sand, commercial product).
206.Believing the side stand is sufficient: It is not a safe support device for working under the motorcycle. Use a lift table or a centre stand with support.
