The men work for a subcontractor, Mar Sal Plumbing and Heating out of Ozone Park in Queens. They were working in the sixth floor science lab classroom when the blast occurred.

"Plumbing - Alteration Type 2. Provide hot and cold water, sanitary, and gas connections from the cellar to science equipment on at 6th floor. Provide mechanical ventilation of fume hoods. Replace existing acid neutralization tank. Replace lighting in 6th floor science room and in ceilings of rooms affected by plumbing work on floor floors."
