Top Safe & Low-VOC Spray Adhesives for Reefer Trailer Wall Repairs

Working in reefer trailer repair is a unique environment when it comes to spray adhesives. Because of the enclosed and confined space, large panels, ventilation challenges and potential for chemical exposure, there are some special considerations for human safety risks when using  adhesives. We'll take a look at those considerations, as well as evaluate the safest spray adhesives for reefer trailer repair.

Spray Adhesive Safety Considerations for Reefer Repair

What are the unique safety considerations for reefer repair? Let's dive in.

Proper Ventilation to Prevent Inhalation Hazards

Many spray adhesives contain volatile organic compounds (VOCs) and flammable solvents that can accumulate in a confined space like a reefer trailer. Without proper airflow, workers risk inhaling toxic fumes, which can cause dizziness, headaches, nausea, respiratory irritation, or long-term lung damage.

• Always keep doors open during application.
• Use portable exhaust fans or forced air ventilation to remove fumes.
• Wear an NIOSH-approved respirator rated for organic vapors (e.g., 3M 6001 cartridges).

Fire and Explosion Risks Due to Flammable Aerosols

Many spray adhesives use flammable propellants (such as acetone or propane-butane blends). A spark from electrical tools, static discharge, or a running reefer unit compressor could ignite the vapors, leading to fire or explosion.

• Turn off all ignition sources, including the reefer unit, before applying adhesive.
• Use low-VOC, non-flammable adhesives when possible.
• Keep a fire extinguisher (Class B for flammable liquids) nearby.

Skin and Eye Protection

Spray adhesives can cause chemical burns, irritation, or allergic reactions upon skin contact. Aerosol mist can enter the eyes, leading to severe irritation, redness, or vision problems.

• Wear chemical-resistant gloves (e.g., nitrile or neoprene).
• Use safety goggles or a full-face shield to protect against overspray.
• Wash skin immediately with soap and water if exposed.

Proper Adhesive Handling & Storage

Improper storage can lead to accidental spills, leaks, or pressure buildup in aerosol cans. High temperatures inside a reefer trailer (especially in warm weather) can cause pressurized adhesive cans to rupture or explode.

• Store spray adhesives in a cool, well-ventilated area, away from heat.
• Never leave aerosol cans inside a closed trailer in hot weather.
• Dispose of empty cans following hazardous waste regulations.

Preventing Slips and Falls

Excess overspray can make reefer floors extremely slippery, increasing the risk of falls and injuries.

• Use drop cloths or masking to control overspray.
• Wear slip-resistant footwear.
• Clean up excess adhesive immediately with appropriate solvents.

While spray adhesives speed up reefer trailer wall repairs, they must be used safely to prevent health hazards, fire risks, and workplace injuries. Proper ventilation, PPE (personal protective equipment), fire safety, and handling procedures are essential for protecting workers during application.

So how do you know which spray adhesives are the safest to use for enclosed reefer trailer repair? You can check out the adhesive properties, technical data sheet, suggested substrate usage, safety features, and benefits. Here we'll discuss three of the most widely used in the reefer repair industry.

Remember, even with low-VOC and non-flammable products, you need to take proper safety precautions for the usage environment. 

Ventilation
Even with low-VOC and non-flammable adhesives, ensure adequate ventilation during application to minimize inhalation of any emitted substances.

Personal Protective Equipment (PPE)
Wear appropriate PPE, including gloves and safety glasses, to protect against potential skin and eye contact.

Storage and Handling
Follow the manufacturer's guidelines for storage and handling to maintain product integrity and ensure safety.

By selecting adhesives with the right safety features and adhering to recommended safety practices, you can effectively mitigate health risks and fire hazards during reefer trailer wall repairs. Keep installer safe and get the job done quickly and effectively!
