Answer 18

Horizontal - bulk storage and able to dispense Cone roof - weak roof to shell seams that break with pressure Open top floating roof - no vapour space like cone roof Covered top floating roof - like a cone roof with a floating top. Also has a version covered with geodesic dome (for flammable liquids) Lifter roof - designed for when vapour pressure builds the roof lifts and relieves it Vapordome roof tank - Vertical storage with flexible diaphragm for vapours Underground - More than 10% uderground. Typically petro products

Answer 31

Non pressure is up to 100psi, pressure is 100-500psi (689 to 3447 kPa)

Answer 32

Class A B C industrial excepted Type C is rare, meant for plutonium, transported by aircraft, able to withstand plane crashes without contamination Excepted, industrial, A, B, C for order of severness

Answer 33

Explosives 1. 1 to 1.6 1. 1 seems to be the most dangerous, 1.6 the least

Answer 34

Vapor pressure greater than 300 kPa at 50C OR is completely gaseous at 20C 101.3 kPa (DOT definition more specific than NFPA) Hazards - thermal, asphyxiation, chemical, mechanical

Answer 35

2. 1 flammable gas 2. 2 nonflammable poisonous gas 2. 3 gas poisonous by inhalation (hazard zones a through d with a being the worst) LC50 less than 200ppm or A and 3000-5000 ppm for D

Answer 36

``` Different definitions for flammable and combustible liquid Flammable - Flash point less than 60C or 37.8C that is intentionally heated for transport Combustible - Flash point between 60C and 93C and does not meet the definition of any other hazard class Hazards are thermal mechanical chemical and asphyxiation ```
