As of June 18, 2010, autobody shops, manufacturers, and distributers in Canada will be required to use waterborne compliant auto refinish coatings or a similar solution to limit VOC emissions into the environment. Automotive body shops that have remaining inventory of non-compliant coatings will be able to use up their inventory as long as it was purchased prior to the implementation date. These new regulations will impact products in Canada as well as products being shipped to Canadian shops.

Paint Booth Fire Protection
NFPA-33 Spray Application for Flammable and Combustible Materials requires an automatic fire protection system for all spray booths. Here are some frequent questions about this paint booth issue. This information is offered as a guide; your local inspector and fire marshal will be experienced in their interpretation and local codes.
- Who do I buy this system from? – These systems are made by only a few certified manufacturers like Amerex, Pyrochem, Anzul and Badger. They can often be purchased through the spray booth seller.
- Can I do the installation myself? – No. Installation should be done by a licensed installer.
- What if I have a wet sprinkler system in the building? – A self-contained system is designed to extinguish a fire in the paint booth, plenums or ductwork, all areas that the building’s system will rarely reach. Some smaller, limited-use open-face paint booths may be approved by your local authorities as being adequately protected with the building’s wet sprinkler system. Consult your local inspector and fire marshal for that specific application.
- Are there size limitations to the booth? – Yes. Open-face spray booths should be no more than 12’ high due to the design limits of these systems. Higher open-face booths can be protected but at a significant cost. The larger the spray booth, the more ductwork and the greater number of fans all add to the cost of the fire protection system.
- What are the maintenance requirements? – After the initial installation, most system providers can be contracted for annual inspections. This annual inspection will include checking the pressure of the chemical tanks, the mechanics of the system, the fusible links (the automatic part of the system) and the control panel. They will apply an inspection tag much like a portable fire extinguisher’s. This contractor should be notified after any trigger event of the system or when any question arises about the system.
- What is the major difference in wet versus dry systems? – NFPA-33 allows either system. The dry system is designed using the same technology as restaurant fire protection system made to work on oil/grease fires, mush like the solvents found in most paints. A wet system simply works with water and may not stop a solvent-laden fire as quickly as the dry system. The dry system should work better in corners, ductwork and plenums. The dry system should be easier to clean up after a suppression event.
Fire protection is one of the main reasons to have a spray booth, along with providing a clean spraying environment, fume/overspray controls and safe lighting. A paint booth owner must complete the process of building a spray booth by making sure that a certified installer completes a pre-designed fire protection system and that the system is maintained.

System for Cleaning Paint Booth Air
Tools USA responded to a question on a Collision Hub Blog that we wanted to share on our blog.
The paint booth user needed to replace their system for cleaning air used in their spray booth. One company suggested they would need a refrigerated dryer.
Air refrigerators and air conditioners are equipment used for extreme environment conditions or super-sensitive spray applications. Some of these conditions may be very long periods of super-high humidity, very dirty air supplies, and nano-technology paint materials.
There are spray booths in all parts of the USA, spraying the vast majority of paints and powders, without using this expensive high-end equipment.
We recommend our most popular dryer “THE EVAPORATOR 10 LB DESICCANT AIR DRYER“. We sell a lot of these to shops for use on their paint booth just for cleaning the air prior to going into their paint gun.
Here are some of the benefits of this dryer.
• Oil-free air
• Super low relative humidity – 1.5%
• Can be mounted on wall or floor
• No electrical parts or motors to explode
• 95 times dryer than a MOTO GUARD filter
• 81 times dryer than a LAMANS Filter/Dryer
• 81 times dryer than a DeVILBLISS Filter/Dryer
• 26 times dryer than a REFRIGERATED Dryer based on 70 F entering air 100PSI
• FOR SHOP COMPRESSORS
• 3 YEAR WARRANTY
Fire Prevention in Spray Booths
Top 10 Really Bad Ideas for Spray Booths (or What a great way to have a fire!!)
- Using any electrical device in a paint booth.
- Thinking how cool it would be to have an electrical outlet in the spray booth wall.
- Smoking in a spray paint booth.
- Grinding or welding in a paint booth.
- Not using a licensed electrical contractor to wire the booth lights and fan.
- Not performing routine maintenance of cleaning the walls/ceilings/floor or changing filters.
- Not installing an automatic fire suppression system.
- Not assembling the spray booth as shown in the manual.
- Using your spray booth to store excessive paint or other combustible materials.
- Not training your booth operators about fire safety.
The NFPA-33 standard defines the safety requirements for spray booths. This standard is available through Techstreet. This is a good investment that will save you money, but you might not have that great fire story to tell your friends.

Spray Booth and Paint Booth Filters
Spray Booth Filters need to be changed regularly to maintain operational efficiencies for your Paint Booth.
The following are the different type of paint booth filters:
1. Exhaust Filters – Trap any leftover pollutants prior to the air entering the atmosphere. These spray booth filters are typically changed after 50-100 working hours.
2. Intake Filters – Cleans the air coming into the spray booth.

Spray Booth Maintenance
It is necessary to maintain your spray paint booth in order to have the booth operating efficiently and provide a high quality product for your auto body shop customer. Shop Paint Booths.
Maintenance of the following areas is important.
1. Lighting – Color and brightness inside the booth should be maintained. Over time, this will deteriorate and even though they may appear operational, the lights might not be in high working order. Consider replacing light bulbs on a regular basis or purchasing a light meter to test the lights frequently.
2. Spray Booth Motor – If you have a non-lubricating motor, you will need to grease the motor. Newer paint booths are sold with self-lubricating motors. Fan motor belts need to be replaced annually and inspected during the year.
3. Cleaning the Spray Booth – A powder coated booth is the easiest booth to clean since it can be washed off when overspray accumulates. The white finish allows dirt to be brushed off the interior walls and captured in the filters. The paint booth should be operating during the cleaning so the filters will capture dust.
4. Interior Paint Booth Temperature – Some paint manufacturers recommend keeping the spray booth between 68 and 70 degrees while the booth is operational. Paint booths with an air make up unit will come with a temperature gauge. Some paint booths will come with a temperature gauge. Adjustments may need to be made depending on the temperature of the object being painted and the air surrounding it. Spray booth temperature can be easily increased or decreased to accommodate changes.
5. Spray Booth Filters – The filters should be changed to prevent pollutants from entering and exiting the spray booth. Excessively dirty filters can lead to an imbalance of air flow in the booth. It is not recommended to clean the filters with air or water to try to make them last longer.
6. Paint Booth Air Flow – Maintaining proper air flow will enhance the paint drying time. Air flow can be tested by generating smoke inside the booth and watching the pattern and speed at which the smoke exits the booth. Keep in mind that the larger the item in the spray booth, the higher the air flow will be.

Requirements for Fire Suppression in Paint Booth
All of Tools USA’s spray booths are designed to comply with the NFPA-33 requirement for an after-market fire suppression system that:
– complies with NFPA-33 Chapter 9
– is installed by a licensed contractor who can work without being on top of the spray booth
– is not installed in a manner that threatens the structural integrity of the paint booth by removing excessive material or placing excessive weight on the top of the booth
– does not create excessive obstructions within the spray booth that would accumulate overspray
– is inspected annually by a licensed contractor.
The vast majority of our spray booths are complimented with dry-chem suppression units from experienced manufacturers who specialize in fire protection. These units comply with NFPA-17 and NFPA-33 when installed by a licensed contractor. They allow quicker fire suppression without the threat of electrical shock, quicker restart after deployment and better fire suppression in the exhaust ducting.
The wet sprinkler system is a valid alternative if required by local code or specific building factors.
Tools USA strongly recommends that proper installation of the paint booth, proper training of operators and safe storage/mixing of materials to be sprayed per EPA, NFPA and OSHA codes as the best method of reducing the chance of fire or explosion in your spray paint booth.
Is Your Spray Booth Working Properly?
It is critical to ensure your paint booth is working properly at all times to gain the greatest operational efficiencies as well as provide a safe environment for the workers. A properly working booth will provide safety, clean environment, appropriate lighting, fire protection, faster drying for paint, and as an option, temperature control.

Why buy a Spray Booth?
There are many reasons to buy a spray paint booth rather than just designating a portion of your collision auto body shop to “painting”. The primary reason is that many states require a spray booth. The spray booth provides a specific clean space to ensure proper paint application as well as directs all the hazardous materials away from the work area through the use of proper filters.
