During performance of electrical work requiring use of 40 Cal Arc Flash PPE (including hood), symptoms of breathlessness, lightheadedness, and confusion were experienced by an electrician. As this type Personal Protective Equipment (PPE) had been worn numerous times without incident, the electrician did not associate this type of PPE with any risk factors; the symptoms were ignored and judgment doubted. Research revealed these symptoms (potential oxygen deprivation) have been experienced by others across industry, resulting in manufacturers creating different types of hoods. Reviews of PPE improvements can identify potential unintended hazards or consequences experienced by others. Include this information in pre-job meetings so workers are better equipped to acknowledge alerts and perform recovery actions.
