Mechanical operators providing roadside assistance face significant risks when handling flammable liquids, from extraction through to final disposal as waste. They must also ensure their own safety and that of other road users in a high-risk road environment. This article sets out the safety requirements, applicable regulations and responsibilities for these operations, ensuring compliance with legal and environmental standards.
1. Extraction and Handling of Flammable Liquids
1.1. Safety Measures During Extraction
- Fire-resistant materials: Tanks and work areas must be built from non-combustible materials that do not give off toxic fumes at high temperatures 1.
- Adequate ventilation: Extraction systems are required to prevent the build-up of flammable vapours, especially in enclosed spaces 1.
- Ban on ignition sources: No smoking, avoid sparks and isolate electrical equipment that may generate heat 13.
- Personal protective equipment (PPE): Flame-resistant gloves, safety goggles and fire-retardant clothing are mandatory 1.
1.2. Storage and Transport
- Certified containers: Use airtight, fire-resistant containers labelled in accordance with the applicable regulations 1.
- Filling limits: Do not exceed 90% of capacity to prevent spills due to thermal expansion 1.
- Hazard identification: Pipes and tanks must be marked with colour codes and hazard symbols (ADR/GHS) 5.
1.3. Waste Management
- Ban on discharges into drains: Spills must be contained in collection pits and disposed of through authorised waste managers 115.
- Hazardous waste register: Comply with the Reglamento de Transporte Terrestre de Materiales Peligrosos for final disposal 15.
2. Safety of the Mechanical Operator on the Road
2.1. Working Environment and Road Regulations
- Emergency signage: Use of reflective warning triangles, hazard lights and high-visibility vests 6.
- Coordination with the authorities: In the event of major incidents, contact CAPUFE (074), Ángeles Verdes (078) or Emergencias Nacionales (911) 6.
- Compliance with the Ley General de Movilidad: Prioritise road safety, avoiding obstructions and using refuge areas 6.
2.2. Safe Repairs
- Prior inspection: Check for leaks, structural damage and the condition of electrical systems before intervening 12.
- Fire protection: Keep ABC extinguishers and inert materials (sand) in the work area 13.
- OSHA certification (for tow trucks and heavy equipment): Operators must be trained in load limits and emergency protocols 12.
2.3. Legal Responsibility
- Compliance with standards: The Secretaría del Trabajo y Previsión Social and SEMARNAT regulate penalties for non-compliance in the handling of hazardous materials 115.
- Civil liability: Negligence in procedures can result in fines or claims for environmental damage or injuries 12.
Conclusion
Mechanical operators must integrate industrial safety protocols, environmental regulations and road safety prevention into their procedures. From the safe extraction of fuels to the response on the road, every step demands precision and legal compliance. Ongoing training and the use of suitable PPE are key to minimising risks and protecting lives.
