Working with an open flame and high temperatures naturally leads to any number of hazards. These include:

• Spread of fire
• Burning or injuring oneself due to improper handling of the torch
• Major inhalation of smoke or fumes
• Major damage to other materials or surface around

These hazards don’t mean that the process is inherently dangerous. They simply provide a warning: one must be very careful, aware, and prepared.

Safety Precautions

1. Choosing the Proper Work Area
Do the charring in open air, or in a well-ventilated, fire-safe place like a roadside or concrete area. Never perform the work indoors or near any flammable substances such as dry grass or paper.

Keep a fire extinguisher ready, or at the very least, a bucket of water or a garden hose in case of emergencies.

2. Wear Protective Clothing
Protect yourself against heat, sparks, and fumes with:

• Heat-resistant gloves
• Eye protection/safety goggles/face shield
• Long-sleeved shirts made of natural material (ones that do not include synthetic fibers, which can melt)
• A respirator/mask (above all when charring treated wood or in still air)

3. Use a Suitable Torch
A propane torch can be used for wood charring or any outdoor purpose. Ordinance type usually selected are:

• Weed torches, 
• Roofing torches, and 
• Handheld propane torch with flame adjustment.
• The torch should be connected in proper manner, should not be leaking-FL; one should use it strictly by following the manufacturer safety directions.

4. Preparing the Wood Correctly
Ensure the wood has been thoroughly dried, cleaned of varnish, paint, or stain that could emit harmful fumes. Choose for Shou Sugi Ban the untreated softwoods such as cedar, pine, or spruce.

Place the wood on an inflammable surface like bricks, concrete slabs, or metal sawhorses.  

5. Burning with Flame Control
Face the danger of over burning or of incineration away by taking it slowly and steadily with the torch. Your aim is an even, consistent char, not a wild menace of flame. 

Once the desired char level is reached, the wood must cool down entirely before one can move further by applying oils or sealants.

Safety After the Burn: Post-Charring
After completion:

• Set the torch and propane away from heat or flame sources safely.
• Dispose of the charred debris or ashes properly.
• While curing, keep the wood in a dry, ventilated place.
