Which of the following is NOT a source of additional stress associated with the use of CPC suits?

The correct answer is improved mobility, as this attribute is not associated with stress when using Chemical Protective Clothing (CPC) suits. In fact, one of the key concerns when donning these suits is that they often restrict movement and can impede the wearer’s ability to perform tasks effectively.

In contrast, reduced visibility, added weight, and heat stress are significant stressors that individuals wearing CPC suits must manage. Reduced visibility can hinder situational awareness and the ability to communicate effectively. The added weight of the suit can increase fatigue and physical strain over time. Heat stress occurs due to the insulating properties of most CPC suits, which trap heat and can lead to overheating, causing additional physical stress on the user. Therefore, while the other options contribute to the overall stress experienced when using CPC suits, improved mobility does not align with the challenges posed by these protective garments.
