Complete Show Notes
0:55 Question #1 – What is an IBC?
- IBC stands for intermediate bulk container (usually referred to as a tote) – can be flexible or rigid
- Found in the United Nations recommendations on the transportation of dangerous goods
- Can carry anything from aviation fuels and gasoline to corrosives and pellets
- Also come in the form of sacks, walled bags, and 55-gallon drums
- Capacities up to 400 gallons and pressures up to 100 psi
2:10 Question #2 – Do We Need to Wear Long-Sleeved Shirts and Pants Under Level A Suits?
- You don’t have to wear any kind of ensemble inside your Level A, but people usually do because it’s comfortable (and recommended)
- OSHA 1910.120 provides suggestions on what to wear with/inside your Level A – includes hardhats, long-sleeved pants, long-sleeved shirts, and more – but they’re all listed as being optional
- Mike wears scrub pants inside his Level A – keeps the rubber of the suit from rubbing up against your skin and pinching you
- NFPA 1991 briefly describes undergarments, but only in the section on the flame test where a dummy is wearing an undergarment with his Level A
4:55 Question #3 – What’s the Difference Between CAS Numbers and RTECS Numbers in the NIOSH?
- Chemical Abstract Service (CAS)
- Lists over 129 million organic and inorganic substances and over 67 million protein and DNA sequences
- Registry of Toxic Effects of Chemical Substances (RTECS)
- Database of toxicity information for around 152,000 chemicals
6:10 Question #4 – How Do We Stay in Compliance with New NFPA Garment Standards?
- New standard only applies to suits made and purchased after the publication of the standard
- You don’t have to get rid of your existing suits just because they don’t satisfy the new standard – just make sure they’re in working order and satisfy the standard they were created under
