Safety Norms: Automotive and Aerospace Engineering

1Purpose, Scope, and Safety Principles

This document sets baseline safety norms for anyone performing automotive and aerospace engineering activities. Its purpose is to prevent injury, fire, toxic exposure, property loss, and harm to the public, and to support compliance with applicable law and approved procedures. It applies to vehicle and component workshops, chassis and powertrain test cells, composite and metal fabrication areas, battery and electronics bays, wind tunnel and rig facilities, and any off-site track, road, or flight-line activity organized by the institution.

Safety principles apply throughout. Hazards are eliminated where possible, then substituted with safer materials or methods, then isolated, then engineered out with guards and interlocks. Administrative controls such as training, permits, and supervision come next, and personal protective equipment is the last line of defense. In this document, the word must marks a mandatory norm, while should marks a recommendation that may be adapted only with competent approval.

2Roles, Competence, and Accountability

The program owner, usually the department head or laboratory director, must appoint a named safety lead for each facility and each significant activity. The safety lead approves hazard assessments, authorizes operators, reviews incidents, and has authority to stop work when conditions are unsafe. Supervisors confirm that each person is competent for a task before allowing unsupervised work. Competence means documented training, demonstrated skill, understanding of the hazards and controls, and fitness for the role as determined by qualified occupational health staff where required.

Every individual is accountable for following these norms, reporting hazards, refusing unsafe instructions, and never operating equipment without authorization. Contractors receive the same induction as staff and must show their own qualifications and insurance records as local rules require.

• Only persons with written authorization may operate hoists, lifts, lathes, mills, grinders, autoclaves, dynamometers, engine test cells, high-voltage systems, or compressed gas systems.
• Learners work under direct supervision until the supervisor records their competence in writing.
• Anyone may stop work if they believe continuing creates imminent danger, and no one may be penalized for doing so in good faith.
• Supervisors must not ask anyone to bypass a guard, interlock, permit, or isolation step to meet a schedule.

3Activities, Hazards, and Risk Assessment

Typical activities include engine and drivetrain dynamometer testing, brake and suspension rig work, vehicle lifting and body repair, battery pack assembly and cell testing, fuel system handling, carbon fiber layup and curing, machining of aluminum and titanium, hydraulic and pneumatic rig operation, avionics bench testing, wind tunnel runs, and ramp or flight-line support. People exposed include students, technicians, engineers, drivers, pilots, visitors, and bystanders near roads, tracks, or airfields.

Risk assessment is a written process. The assessor identifies each hazard, the people or assets exposed, the likelihood and severity of harm, existing controls, and additional controls needed. Risk is rated with the institution's approved matrix. Any task rated high or above must not proceed until the safety lead approves the controls. Assessments are reviewed whenever equipment, personnel, materials, or the process changes.

• Stored energy: raised vehicles, springs, pressurized hydraulic and pneumatic lines, flywheels, and gas cylinders can cause crushing, whipping hose injuries, and sudden release.
• High-voltage hazards: traction batteries and power electronics can cause electric shock, arc flash, and thermal runaway. Only trained persons may work on them.
• Flammable liquids: fuel, oil, and solvent vapors near ignition sources can cause fire and explosion.
• Moving parts: engines, drive shafts, cooling fans, propellers, rig couplings, and machine spindles.
• Dust and fumes: composite fibers, resin and hardener chemicals, and metal fines can irritate or be inhaled.
• Noise, heat, and vibration from engine tests, turbines, grinders, and compressed air tools.
• Public exposure: road tests and airfield activity can expose bystanders to vehicles, debris, and noise.

4Preventive Controls and Safe Work Practices

A permit to work is required for hot work, confined space entry, high-voltage work, work on pressurized systems, test cell operation with fuel or running engines, and any task that bypasses a guard or interlock. The permit names the task, location, hazards, isolations, controls, authorized persons, and expiry time. The issuing authority verifies controls before work starts and closes the permit when work finishes.

Energy isolation follows a written lockout and tagout procedure. Before maintenance, the operator stops the equipment, isolates electrical, pneumatic, hydraulic, fuel, and thermal sources, applies a personal lock and tag, releases stored energy, and tests that the equipment will not start. Only the lock owner removes a lock. Vehicles raised on a lift are held by the lift's mechanical locks, and anyone working beneath a vehicle uses approved stands in addition to the lift. A jack alone is never sufficient support for work under a vehicle.

Machine guarding must be in place before operation. Fixed guards stay fixed during operation, and interlocks must never be defeated with tape, wedges, or jumpers. Test cells use physical barriers, emergency stops within reach, and a marked exclusion zone. Rotating components are never touched while moving. Fuel and exhaust systems run only in ventilated areas with approved extraction, and gas monitoring is used where the risk assessment requires it.

• Must: complete a written pre-start checklist for every rig and test cell, covering guards, fluids, restraints, fire equipment, and emergency stops.
• Must: keep at least one trained person with a clear view of any running engine, rig, or machine.
• Must: treat every high-voltage conductor as live until a qualified person verifies isolation with a suitable tested instrument.
• Must: use lifting equipment with current inspection status and never exceed its rated capacity.
• Must: store fuels and solvents only in approved containers, away from ignition sources and drains.
• Should: prefer machining fixtures and enclosed cutting methods that keep hands away from moving tools.
• Should: clean composite and metal dust with local extraction rather than compressed air.
• Should: rehearse test cell shutdown and fire response at intervals set by the local procedure.

5Equipment, Environment, Information, and Protective Safeguards

Minimum PPE in workshops is safety glasses with side protection and closed, slip-resistant footwear. Hearing protection is required where the noise assessment identifies exposure above the threshold set by local regulation. Grinding and machining require face shields in addition to glasses. Chemical handling requires gloves selected against the supplier safety data sheet and suitable eye protection. Composite and resin work requires respiratory protection chosen through the institution's fit-tested program. Loose clothing, jewelry, and long hair must be controlled near rotating equipment.

Hazardous materials are stored by compatibility in labelled, approved cabinets. Waste oil, coolant, solvents, batteries, resins, and contaminated rags are collected in labelled containers and disposed of through licensed contractors. Spills are contained with absorbent materials, reported, and cleaned by trained staff. Discharges to drains are prohibited. Engine exhaust is ducted to the outdoors or to approved extraction. Road and test noise and emissions must follow local permits and consider nearby residents.

Test data, design files, calibration records, and vehicle or aircraft system information may be commercially sensitive or subject to export rules. Access is limited to authorized users, and passwords are never shared. Telemetry and diagnostic tools connect only to approved networks. Software on controllers and test equipment changes only through approved change control. Records about drivers, test subjects, or staff are handled under the institution's privacy policy and applicable data protection law, which varies by jurisdiction.

• Confirm that extinguishers, eyewash stations, and first aid kits are present, labelled, and unobstructed before each session.
• Keep exits clear and marked in every test cell and workshop.
• Verify current requirements for PPE, noise, emissions, and waste with competent authorities or qualified professionals.

6Incident, Near-Miss, and Emergency Response

Any injury, illness, fire, spill, release, equipment failure, or near miss must be reported to the supervisor immediately and entered in the incident system within the timeframe the institution sets. Near misses are reported because they reveal control weaknesses before someone is hurt. Reports describe what happened, who or what was exposed, actions taken, and recommended corrective actions. Good faith reporting is never grounds for blame.

Emergency arrangements are posted in every workshop, test cell, and flight-line area. Postings show emergency numbers, assembly point, extinguisher and eyewash locations, first aid kit, and the emergency stop. Trained first aiders are identified on each shift. Emergency services are called before anyone attempts rescue from energized equipment, confined spaces, or hazardous atmospheres. Untrained persons must never enter a fire, a high-voltage hazard, or a confined space to attempt rescue.

• If safe to reach, press the emergency stop and isolate the energy source.
• Evacuate, account for everyone at the assembly point, and tell responders about anyone unaccounted for.
• For a battery or vehicle fire, keep people clear, follow the approved response plan, and notify fire services; do not handle damaged battery packs without specific training.
• For a fuel or chemical spill, remove ignition sources, ventilate if safe, and contain with approved materials.
• Use a fire extinguisher only if trained, the fire is small, and an exit is behind you.
• Escalate to the safety lead and program owner, and notify aviation, transport, or environmental authorities where local rules require.

7Records, Training, Inspection, and Review

Training records show who was trained, in what, when, by whom, and the assessment result. Risk assessments, permits, inspection reports, calibration certificates, lifting equipment examinations, and maintenance logs are kept for the period required by local law and institutional policy and remain available to authorized auditors.

The safety lead carries out inspections on the schedule set in the local procedure. Inspections cover guards, interlocks, extinguishers, eyewash stations, extraction, lifting equipment, gas cylinders, electrical leads, and housekeeping. Defective equipment is tagged out of service until repaired and verified. Monitoring includes incident and near-miss trends, audit findings, and user feedback. The safety committee reviews these results and updates the norms. Manufacturer manuals, service bulletins, and applicable vehicle or airworthiness requirements are tracked and applied where they govern the institution's activities.

• Refresher training follows the interval in the local procedure and is repeated after any change in equipment or process.
• Maintenance is performed only by authorized staff using current manufacturer instructions or approved alternatives.
• This document does not state legal requirements. Verify current versions of laws, standards, codes, and manufacturer instructions with competent authorities or qualified professionals.

Implementation checklist
