Risk Assessment

Factors of Risk During Filming on Set:

• Audiences? No, the only people present were employees and myself.
• Camera Equipment? Only if it was set on the floor however my rig was small and hand-held.
• Confined Spaces? No the factory was nice and open with enough space for each section. 

Note - My different style of answering the question but it still answers it...

• There was more than a normal supply of gas and electricity but it is due to high powered equipment, which is handled safely by professionals.
• There was flammable materials but it was never a problem.
• There was a lot of machinery but it was only used by the employees. 
• There was a lot of noise but not enough to use ear plugs.
• There is no night operation.
• There is no special effects.
• All vehicles move very slowly and if not it is due to them not being in the way of people working.
• There was no working over seas conducted. 

Overall the environment was safe to me but there are dangerous things there. However, as these were handled by professionals I was not at risk what-so-ever as it was treated strictly and it was obvious that non-professionals wouldn't try to use the equipment.
