Good morning-- First, for highly toxic materials, our Packaging Dept., which is measures out prepack units from a bulk container, typically uses neoprene outer gloves with a Silver Shield(R) glove as an inner liner. They also wear other PPE to prevent inhalation or contamination of skin or clothing. The PPE requirements are dependent on the hazards associated with a particular chemical (examples could be supplied breathing air, aprons, sleeves, boot covers, etc.). Second, the MSDS indicates "Handle with gloves", rather than a more specific recommendation, because the glove choice (& indeed all PPE) is so dependent on the user's specific task. According to OSHA's Hazard Communication Standard, MSDSs have to be written to cover situations ranging from small amounts to commercial quantities. The PPE requirements are dramatically different for the safe handling of a 5g bottle versus the safe handling of a 55 gallon drum (or larger).
