Bleaching local

High pressure Low/no flow - chlorine gas supply line for bleaching line A (linked from 5.2) High temperature (linked from 4.3) High pressure - chlorine railcar (linked to 1.5) Potential damage to the vaporizer if isolated from the relief valve on the chlorine railcar (linked to 4.9) Local pressure indication ... 

Skin Contact Don respiratory mask and gloves remove victim from source immediately and remove contaminated clothing decontaminate the skin immediately by flushing with a 5% solution of liquid household bleach wash off with soap and water after 3-4 min to remove decon agent and protect against erythema seek medical attention immediately to prevent systemic toxicity, decontamination should be done as late as 2 or 3 h after exposure even if it increases the severity of the local reaction further cleans with soap and water. 

Skin Contact Don respiratory mask and remove contaminated clothing wash contaminated skin with copious amounts of soap and water immediately using 10% sodium carbonate solution, or 5% liquid household bleach rinse well with water to remove decontamination if local sweating and muscular symptoms occur, administer an intramuscular injection with the MARK I Kit seek medical attention immediately. 

Metal-ion catalysis of hydrogen peroxide decomposition can generate perhydroxyl and hydroxyl free radicals as in Scheme 10.26 [235]. The catalytic effects of Fe2+ and Fe3+ ions are found to be similar [235]. It is not necessary for the active catalyst to be dissolved [237], as rust particles can be a prime cause of local damage. The degradative free-radical reaction competes with the bleaching reaction, as illustrated in Scheme 10.27 [237]. Two adverse consequences arise from the presence of free radicals ... 

Interestingly, the irradiation of the same solution at the (local) absorption band of chloranil (/ vQ) results in a much faster and complete bleaching of the solution to yield identical retropinacol products (equation 56).
