During storage, transport and use personal protective equipment (PPE) for fall arrest may come into contact with chemical substances. While being transported, for example, in a car PPE may come into close proximity with engine oil, spare batteries or AdBlue. When used in industrial climbing, contact with chemical substances is also an issue, for example when cleaning special equipment or facilities or when handling motorized tools while climbing trees. Plastics are particularly affected by damage, as they are far more susceptible to chemical effects than metals. We want to address the question of how chemicals affect textile PPE and which substances are to be regarded as particularly critical.
IN LIGHT OF CURRENT EVENTS: One of the many consequences of the Corona epidemic is the increased use of disinfectants. In the rental area of climbing halls but also in private, the question for many climbers is whether and how such substances affect their ropes, slings, in short, their PPE. Our studies have shown, for example, that sargrotane does not reduce the strength of polyamide. Above all, strong acids and bases lead to changes in the properties of plastics. However, the relationships between the influence of chemical substances on textile PPE are complex and not easy to assess. You can find out more here in the article.
