In order to be an effective thermographer, one must be trained in the following:

• Theory and construction of the object or system being inspected
• Infrared theory and heat transfer principles
• Use and operation of infrared imaging equipment
• Non-contact temperature measurement error sources and how to avoid or correct for them

In addition to the above, qualified thermographers must also be experienced with inspecting the subject system. When all things are considered, effective thermographers need considerable training and field experience. Making thermography look simple is a true testament to the skills of a professional thermographer.

The next time you hear the dismissive claim that thermography is easy, remember, it is only easy after someone has invested considerable time and effort to learn the art and science of the trade. In a magic show, the magic comes from the magician, not the wand. In thermography, the magic comes from the thermographer.

• Identify all potential tripping and fall hazards before work starts
• Look for fall hazards such as unprotected floor openings/edges, shafts, skylights, stairwells, and roof openings/edges
• Use appropriate fall protection equipment; inspect equipment for defects prior to each use
• Never use boxes or chairs in place of an appropriate ladder or stepstool
• Secure and stabilize ladders before climbing them; never stand on top rung or step of a ladder
• Use handrails when going up/down stairs
• Practice good housekeeping – keep floors dry and free of clutter such as cords, hoses, and cables
• Keep walkways free of snow and ice

Lastly, be sure to use sturdy footwear appropriate to the task. Work boots and shoes should be laced and tied to prevent tripping and to afford proper support. When it comes to fall protection, an ounce of prevention is worth a pound of cure.
