A conviction check stuff PVC gloves, fluorescent lamp, feeler gauge, appearance check tool, ruler, plastic gasket, insert, high-density foam box, mask, black oil. B. Conditional inspection 1. According to 800lx Lux fluorescent lamp; 2. Judging to check on the operating table, clean level; 3. Metal shrapnel natural level operation table to grasp each piece of sentence should not be artificially squeezed; 4.
