4,4-dimethoxybutylamine

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Remove victim to fresh air. If breathing is impaired or if

it has stopped give artificial respiration; supplemental

oxygen should be given if available. Ensure the victim does

not aspirate vomited material and that mucous does not

obstruct the airway. Seek medical attention. Other: The

product has similar effects to those of ammonia and is

highly injurious to all tissues. Chemical pneumonitis,

pulmonary oedema, laryngeal oedema and delayed scarring of

the airway or other affected organs may occur following

exposure. There is no specific treatment. Clinical

management is based on supportive treatment, similar to

that for thermal burns. Victims with major skin contact

should be maintained under medical observation for at least

24 hours due to possibility of delayed reaction.

Emergency measure - Eyes: Flush eyes immediately with large volumes of water for at

least 15 minutes ensuring that the eye is irrigated. Obtain

prompt medical assistance.

Emergency measure - Skin: Flush the affected area promptly with large quantities of

water for at least 15 minutes. Cover the affected area with

a sterile dressing, do not apply grease or ointments.

Remove any contaminated clothing and launder before reuse.

Leather absorbs the substance very rapidly, so any

contaminated leather wear must be discarded.

Emergency measure - Ingestion: Do not induce vomiting. Seek immediate medical attention.

Fire-fighting measures

Recommended extinguishing agent: Recommended extinguishing agents: Carbon dioxide, water

spray, dry chemical or foam are suitable. Water-fog is also

useful in cooling fire-exposed tanks and in dispersing

vapours.

Product arising from burning: Products arising from pyrolysis: Products of combustion may

contain oxides of carbon and nitrogen.

Protective equipment: Protective equipment: A self-contained breathing apparatus

with butyl-rubber complete body protection is recommended.

Accidental release measures

Emergency measures in case of spillage: Remove all sources of ignition, avoiding inhalation of

vapours. Wear butyl-rubber protective clothing and a NIOSH

approved self-contained breathing apparatus. Dike spills

and cover with sodium bisulfate to neutralise the product.

Spray the affected area with water and scoop up into steel

drums for disposal by incineration or landfill. Prevent

spilt material from entering water systems.

Handling and storage

Handling: Lines to reactors for coating formulation preparation must

be enclosed. Work areas should be well ventilated (keep

vapour concentration below a level which is irritating).

Emergency showers and eye baths should be readily

accessible. Persons handling the substance should wear a

NIOSH approved full facepiece, air-supplied or

self-contained breathing apparatus or air purifying

respirator to avoid inhalation of vapours. Cartridges,

where appropriate, should be MSHA/NIOSH approved TC-23C-287

units. Wear chemical safety goggles and plastic face

shields. Contact lenses should not be worn. Hands and body

should be protected using cuffed butyl-rubber gloves, apron

and boots.

Storage: Store in 55 gallon (c.a. 250 litre) steel drums to US DOT

17E and use nitrogen blanketed storage. Protect the

containers against physical damage and store away from

oxidising agents in an adequately ventilated area to avoid

build-up of vapour.

Special provisions / remarks

Remarks:

Transport: US DOT alkaline corrosive NOS NA 1719. The substance is
also a combustible liquid, class IIIB according to OSHA
standards. [(29 CFR 1910.106), flash point between 37.8 and
93.3 deg C]

SpecialProvisions

Stability and reactivity

Danger other than fire: Other dangers: The substance may react violently with

oxidising agents.

Chemical reaction with water: Chemical reaction with water: None reported (may slowly

hydrolyse to the corresponding aldehyde, especially in the

presence of acids).

Disposal considerations

Industry - Possibility of recovery/recycling: Recovery of contaminated or uncontaminated material can be

achieved by distillation if collected as a bulk spill.

Industry - Possibility of neutralisation: The substance can be neutralised with sodium bisulfate.

Industry - Possibility of destruction: controlled discharge: Landfill disposal is acceptable only where landfill sites

are approved to receive chemical wastes. Amine containing

wastes may present longterm environmental hazards, thus

landfill is less acceptable than incineration.

Industry - Possibility of destruction - incineration: Recommended method, however waste gas treatment to remove

nitrogen oxides should be fitted.

Industry - Possibility of destruction - water purification: The substance should not be directly discharged into waste

water systems. However, disposal via industrial or

municipal waste treatment systems can be used depending on

the quality and quantity of waste to be treated, the

treatment plant capability and discharge water quality

standards.

Public at large - Possibility of recovery/recycling: The substance will only enter the public domain in the form

of articles, that may be disposed of as domestic waste.
