Category	Description
Z	Noxious Liquid Substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a minor hazard to either marine resources or human health and therefore justify less stringent restrictions on the quality and quantity of the discharge into the marine environment.

1 CLASS 3.1
FLAMMABLE LIQUIDS, FLASHPOINT BELOW -18°C Closed Cup., NOT COVERED BY OTHER SCHEDULES; MISCIBLE WITH WATER*
2 CLASS 3.2
FLAMMABLE LIQUIDS, FLASHPOINT BETWEEN -18°C AND 23°C Closed Cup., NOT COVERED BY OTHER SCHEDULES; MISCIBLE WITH WATER*
3 CLASS 3.3
FLAMMABLE LIQUIDS, FLASHPOINT BETWEEN 23°C AND 61°C Closed Cup., NOT COVERED BY OTHER SCHEDULES; MISCIBLE WITH WATER*

Emergency procedures

Action

Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools).

Spillage on deck

Wash spillage overboard with copious quantities of water.

Spillage under deck

Provide adequate ventilation. Collect spillage, where practicable, using absorbent material, for safe disposal.

Fire on deck

Use water spray or dry chemical. Do NOT use water jet or foam. If possible remove receptacles likely to be involved or keep them cool with copious quantities of water.

Fire under deck

Batten down; use ship's fixed fire-fighting installation. Otherwise adopt action as for "On deck".

Special equipment to be carried

Protective gloves and boots.
Self-contained breathing apparatus.
Spray nozzles.

Remarks by UN no.

ETHYLENE GLYCOL MONOETHYL ETHER ACETATE (UN No. 1172)
ETHYLENE GLYCOL MONOMETHYL ETHER ACETATE (UN No. 1189)
Self-contained breathing apparatus not necessary - use goggles for eye protection.

NITROGLYCERIN SOLUTION IN ALCOHOL (UN No. 1204), with not more than 1%
of nitroglycerin.
Water may separate the nitroglycerin from the spillage; this nitroglycerin becomes very sensitive to shock and heat. If spillage under deck, keep it under water and seek advice for safe disposal from the shipper.

NITROMETHANE (UN No. 1261)
In fire, explosion hazard.

2-ETHYLBUTANOL (UN No. 2275)
AMYL BUTYRATES (UN No. 2620)
Self-contained breathing apparatus not necessary - use goggles for eye protection.

NITROGLYCERIN SOLUTION IN ALCOHOL (UN No. 3064), with more than 1% but
not more than 5% nitroglycerin.
Water may separate the nitroglycerin from the spillage; this nitroglycerin becomes very sensitive to shock and heat. If spillage under deck, keep it under water and seek advice for safe disposal from the shipper.
