which of the following best describes who can determine if it is safe to enter a permit - required confined space? * 1 point
supervisor
qualified person
journeyman plumber
code enforcement official

Explanation:

1. For frostbite, rubbing the affected area with snow can cause further damage by increasing tissue injury due to mechanical abrasion and can disrupt blood - flow. Moving to a warm room, removing tight clothing, and immersing in moderately warm water (105°F is within an acceptable range for rewarming) are appropriate first - aid measures.
2. A qualified person has the knowledge and training to assess the hazards and determine if it is safe to enter a permit - required confined space. A supervisor may not have the specific technical knowledge, a journeyman plumber may not be trained in general confined - space safety, and a code enforcement official is more focused on compliance rather than on - site safety assessment for entry.

Answer:

1. Rub the affected area with snow
2. Qualified person
