From pigments to precautions: Ensuring safety in paint factories
“Do I have to paint you a picture?” When it comes to potential catastrophes in any chemical factory, painting a clear picture is exactly what we need to do! Paints and coatings not only have a high risk of ignition that can lead to fire and explosion but can have other far-reaching risks as well.
In August of 2023, an explosion at a paint factory resulted in a serious employee injury and $290,358 in proposed OSHA penalties. Additionally, fire extinguishing foam also spread into nearby waterways, drawing the attention of the Environmental Protection Agency (EPA). Fire officials reported that approximately 700,000 gallons of potentially contaminated water were collected by 30 tanks. In addition to employee injury and financial penalties, these types of incidents can also wreak long term havoc on a company’s reputation with the public.
Learn from others and apply solutions
The cause of the fire is still under investigation, but OSHA’s serious and repeat citations can give us a glimpse of where others can prevent a similar catastrophe.
- General Duty Clause, Section (5)(a)(1)that requires employers to furnish a place of employment which was free from recognized hazards that likely to cause death or serious physical harm to employees.
- Process Safety Management (PSM) requiring:
- Pressure safety valve (PSV) and other vital equipment to be included in system and process designs;
- A thorough process hazard analysis (PHA) identifying the hazards, sensitive chemicals, equipment placement near work areas, and the effects of high ambient temperatures on equipment and processes.
- Written operating procedures that provide clear instructions for safely conducting activities for each covered process, recognizing operation limit deviations, and maintaining the ongoing integrity of process equipment.
- Initial employee training with refresher training provided at least every three years to each employee involved in operating the process.
- Inspections and tests on process equipment as required by regulations.
Avoid painting yourself into a corner
The painting and coating industry brings color and creativity to our world, but it's crucial to prioritize compliance, safety, and risk management. To ensure worker safety and regulatory compliance, here are some essential steps to follow:
- Perform a thorough process hazard analysis (PHA) to assess employee exposures to paint-related risks and compliance with regulations;
- Implement engineering and other controls to improve worker safety, including adding safety devices and switching to non-toxic or non-explosive materials;
- Eliminate fire hazards and ignition sources in volatile areas, including placing saturated rags and materials in covered metal cans and emptying cans daily;
- Reduce the quantity of paint and coating materials stored in facilities to as much as reasonably practical and store in approved cabinets or closed systems;
- Install ventilation systems, fans, or dilution ventilation to minimize the presence of dangerous vapors during the paint or coating application process;
- Prohibit spray painting in tanks, tunnels, or other confined spaces without providing specific, carefully supervised protocols and respiratory protection;
- Confirm processes are intrinsically safe by installing explosion-proof fixtures and requiring bonding and grounding for material transfers;
- Provide appropriate fire suppression and extinguishing equipment;
- Maintain appropriate temperatures for processes and within facilities;
- Create clear written operating procedures for each process that outline safe activities, including operating limits, consequences of deviations, paint mixing, drainage and storage requirements, and emergency response procedures;
- Enforce proper housekeeping including storage of paints, solvents, and coatings; removal of accumulated materials; cleanliness paint mixing areas; and keeping tools and equipment clean;
- Mandate pre-use inspections and frequent inspections of all equipment including safety devices and gauges, process equipment, tools, hoses/fittings/gaskets;
- Require the use of personal protective equipment (PPE) based on hazard assessments, manufacturer instruction, and safety data sheet requirements. PPE for paint operations will typically include:
- Eye protection with chemical goggles;
- Rubber, neoprene, or laminate gloves;
- Respiratory protection with appropriate cartridge;
- Protective clothing or coveralls;
- Safety boots or shoes with non-slip soles; and
- Head protection where overhead hazards exist.
- Provide training and refreshing training when:
- Employees are initially assigned to a job;
- An employees responsibilities change;
- Processes, plans, procedures, equipment, or facilities change; and
- Observations indicate, or whenever the employer has reason to believe, that there are deviations or inadequacies in the knowledge or application of requirements.
Keys to remember: Ensuring the health and safety of paint factory workers keeps employees vibrant and can prevent costly consequences such as non-compliance penalties, environmental blunders, and a compromised company reputation.
