Standby observers, similarly equipped and instructed, shall continuously monitor the activity of employees within such a space.
Signs shall be clearly posted where fumigants, pesticides, or hazardous preservatives have created a hazardous atmosphere. These signs shall note the danger, identify specific chemical hazards, and give appropriate information and precautions including instructions for the emergency treatment of employees affected by any chemical in use.
In the case of containerized shipments of fumigated tobacco, the contents of the container shall be aerated by opening the container doors for a period of 48 hours after the completion of fumigation and prior to loading.
