Safety in Chemical & Oil Storage OperationSEC/SAFETYSTO

Who should attend?

  • This course provides a better understanding of product and equipment risks in order to increase safety behavior in storage and discharge operations.
Audience :
  • Operating personnel (engineers, shift leaders and/or operators) in refineries and petrochemical/chemical plants and any staff involved in operations (maintenance, SHE department).

Level : Proficiency

Course Content


      • Specific hazard inventory and consequences: accident, environmental and health damages.
      • Risk management tools: organizational, human behavior and technical aspects.

      • Flammability:
      • Explosive atmosphere: flammable product occurrence.
      • Ignition sources: hot works, sparks and static electricity, self-ignition temperature.
      • Oxidizers and pyrophoric products.
      • Preventive measures and precautions: hazard operations and behavior to be followed: draining, sampling, product loading or unloading, repair works, motor vehicle traffic, hazardous area, etc.
      • Fluid behavior and related risks:
      • Pressure in a vessel (sphere, tanks, wagons, pipes, etc.) and consequences of a temperature increase or decrease: thermal expansion, vaporization, collapsing due to vacuum, freezing due to pressure drop, BLEVE, boil-over, water hammer, etc.
      • Risk assessment and preventive measures.
      • Risks for human health:
      • Toxicity: risk assessment, main ways of poisoning, prevention and protection.
      • Thermal and chemical burns: equipment layout, product handling, Personal Protective Equipment (PPE).
      • Product interaction: during storage (bulk, barrel, etc.), transport (rail, road, shipment) and hazardous chemical reaction.
      • Hazmat transportation: loading rate, vehicle identification, Material Safety Data Sheet (MSDS), driver certificate, etc.

      • Atmospheric and under pressure storage tanks: different kinds of construction, compressive and vacuum strength, safeguarding equipment (vents, relief valve, hydraulic safety shut-off valves, positive safety valves, etc.).
      • Safety in tank storage operation. Typical incidents.
      • Loading/unloading tank truck, tank wagon, oil tanker, etc.: loading station layout (top or bottom), safe automation and facilities, vapor recovery.

      • Successive stages: utilities used (nitrogen, water, air, gas oil, etc.).
      • Draining-blowdown: depressurization, degassing, inerting.
      • Lockout/Tagout procedure: blinding, ventilation, confined space entry.
      • Works permits: endorsement and responsibilities.
      • Commissioning and start-up.

      • Strict discipline: understanding and compliance with procedure, safety barriers, risk of routine.
      • Employees' involvement: commitment and responsibility.
      • Risk level assessment: accident, near miss, unsafe acts.
      • Field agents: safety department, medical department, health safety and working conditions committees.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • identify and rank the risks inherent to the products handled and stored, and to the equipment used for chemical and oil storage,
  • measure the possible consequences on safety, health and the environment,
  • apply preventive recommended measures,
  • adopt the most appropriate behavior in accordance with the risks.

Ways & Means

  • Workshop: decommissioning and commissioning procedure for a typical unit selected based on trainees’ origins (atmospheric tanks, under pressure storage, recovery unit, etc.).
  • Case studies and analysis of incidents and accidents.
