How should rope and webbing be cleaned if exposed to heavy contaminants?

Using a good industrial detergent and bleach to clean rope and webbing exposed to heavy contaminants is appropriate because it ensures thorough decontamination. Heavy contaminants can include substances like oil, chemicals, or biological materials that may compromise the integrity and safety of the rope, making strong cleaning solutions necessary.

Industrial detergents are formulated to break down tough stains and contaminants effectively, while bleach acts as a disinfectant that helps eliminate harmful pathogens. This combination is ideal for restoring the materials to a condition where they can be safely used again. The use of bleach must be approached with care, ensuring that the rope and webbing are compatible with such harsh cleaning agents, as not all materials can withstand bleach.

Other cleaning methods, while potentially beneficial for lighter cleaning tasks, may not effectively remove heavy contaminants. For instance, using water only might not address the stubborn residue from oils or chemicals. Soap and cold water can be somewhat effective but might lack the necessary strength to deal with more significant contaminants. Deciding not to clean the materials altogether would leave them compromised, posing a risk to safety during rescue operations. Therefore, the recommended approach with industrial detergent and bleach addresses the need for thorough cleaning and safety comprehensively.
