Physical or other invasive/abusive contact with the child may cause mental distress. Allegations of contact may result in legal action.
A child’s inquisitiveness and lack of awareness can lead to injury from filming equipment.
Whether pitch-side filming or at events with high level commentary boxes or observation platforms within a stadium complex, when filming any event at a sports ground an assessment of the potential health and safety risks must be carried out.
Machinery, noise, working from height, members of the public, open stage edges and low lighting during performances all add to the complexity of filming in theatres.
Safety requirements still apply wherever staff are working. Many countries will have their own safety legislation (some with widely differing standards) which may require specific tasks to be done.
Filming in and around controlled water (in swimming pools) reduces the risk of flowing water: e.g. current, cold and disease. The risk is higher when the water is open and flowing.
Winter weather varies hugely across the UK. Check what local weather conditions can be expected, especially if you're filming in remote upland areas.
The adverse health effects of hot weather are largely preventable with some forward thinking and planning.
