A chemical processing plant has an explosive release in one of the mixing areas, causing a fireball that at 16 meters and a radial distance of 24 meters causes a radiant heat exposure of 6.2 (kW/sq.m.)^4/3-min. What is the expected burn effect for workers with exposed skin?
a. Minor irritation
b. 1st Degree burn / severe skin pain
c. 2nd Degree burn
d. 3rd degree (full thickness) burn
Solution | Posted 07/27/20
c. 2nd Degree burn, based on the exposed skin radiant heat exposure as listed in NCEES 10.3.3.2. The fireball diameter and distance are extra information in this problem.
