Genera! contamination of the factory with lead dust has been eliminated by enclosing the entire op* eration in a Urge booth and exhaust* tng a sufficient quantity of air from the enclosure to insure a constant in. ward flow of air from the fartary into the booth. Under these circumstances no practical amount of air could be removed from the booth to redace the lead concentration to a safe level, and therefore it is necessary that the men wortrag therein be proTided with adequate personal protective do vices.
