Below are some questions you should ask yourself when operating around water:
    • How deep is the water?
• How easy is it to fall in?
• How easy is it to get
      out?
• What are the consequences?
• How fast is the water flowing?
• What are the exposure
      dangers?
• What are the obvious and unobvious hazards?
• How cold is the water and the air
      temperature?
    Below are some dynamic considerations:
    • What is the time?
• Can the water conditions change soon?
• What experience
      do I have with the available personnel?
• What are the conditions like now and what does a reliable
      forecast say?
