When working on a temporary platform over navigable waterways in Washington State, safety should be your top priority. Since I do not have any specific documents about working over navigable waterways, I will provide general safety advice. Always wear appropriate personal protective equipment (PPE), including a properly fitted life jacket or personal flotation device (PFD) [1]. Ensure the platform is stable, adequately supported, and has guardrails to prevent falls. Regularly inspect the platform for any signs of wear, damage, or instability. Be aware of the potential for exposure to environmental hazards, such as changing weather conditions, and plan accordingly. If the materials you are working with contain crystalline silica, take precautions to avoid prolonged or repeated inhalation of dust, which can cause silicosis 5, 12.
