The fire and explosion protection measures are primarily to be adapted to more dangerous substances and fire loads in the corresponding work area.
Eye protection: Frame glasses with side protection.
Hand protection:Gloves made from:
Natural rubber / natural latex (NR; 0.5 mm), polychloroprene (CR; 0.5 mm), nitrile rubber / nitrile latex (NBR; 0.4 mm), polyvinyl chloride (PVC; 0.5 mm), butyl rubber (butyl; 0, 5 mm), fluororubber (FKM; 0.7 mm) (breakthrough time> 8 hours, max. Wearing time 8 hours).
The maximum wearing time can be significantly shorter under practical conditions.
Cotton undergloves are recommended when wearing protective gloves!
The protective effect of the gloves against the substance / mixture must be inquired about or checked from the chemical / glove manufacturer, taking into account the conditions of use (see checklist for protective gloves).
The specified glove material relates to an aqueous, saturated solution. Other recommendations may apply for other concentrations.
With natural latex gloves there is a risk of allergies - if possible use other protective gloves. Powdered disposable gloves made of latex are to be replaced by powder-free and low-allergenic gloves.
Long-term wearing of chemical protection gloves is itself a problem Skin hazard (wet work) Avoidance by observing wearing times and / or changing activities.
When wearing chemical protection gloves for a long time, special ones are used against perspiration Skin protection products Recommended before work (see e.g. skin protection agents).
However, these can impair the protective performance of the gloves. The Skin protection plan must consider wearing protective gloves.
Respiratory protection:The wearing of respiratory protection is recommended e.g. for repair work or uncontrolled operating conditions, e.g. full face mask / half mask / filtering half mask with:
Particle filter P1 (white)
Particle filter P2 (white)
It is recommended to use filter devices with a blower and helmet or hood (e.g. TH2P). There are no wearing time limits for this.
Body protection: Dustproof protective clothing.
Information on the selection of chemical protective clothing can be found in a flyer from the PPE department of the DGUV.
After eye contact: Immediately rinse the eyes with plenty of water (at least 10 minutes) with the eyelids open, protecting the uninjured eye.
Ophthalmological treatment.
After skin contact: Immediately take off contaminated clothing, including underwear and shoes; pay attention to self-protection.
Rinse skin with plenty of water.
After inhalation: Take the injured out of the danger area while protecting yourself.
the patient inhales oxygen If breathing is difficult.
After swallowing: Immediate vigorous rinsing of the mouth.
Have the water drink in small sips (dilution effect).
Medical treatment.
Informations for the doctor: Symptomatic treatment (decontamination, vital functions), no specific antidote known.
Young people from the age of 15 may only be employed here:
if this is necessary to achieve the training objective and supervision by a specialist as well as company medical or safety-related care is guaranteed.
Since there is currently no directly appropriate occupational health program available for the substance, it is recommended to use the following DGUV principles based on an examination in the context of occupational health care:
General preventive occupational health care
If the risk assessment makes it necessary to wear respiratory protection, preventive occupational health care must be carried out in accordance with DGUV principle G 26 breathing apparatus.
If, based on the risk assessment, it is necessary to wear chemical protection gloves for more than 2 hours a day (wet work), preventive occupational health care must be offered (preventive measures offered, e.g. based on G 24).
In the case of wet work of 4 hours or more per day, preventive occupational health care must be arranged regularly (compulsory preventive care, e.g. using the DGUV principle G 24).
Do not dispose of even small quantities via the sewer system or garbage can.
According to the AVV, the six-digit waste code is to be assigned to specific sectors, processes, origins or types of waste.
If necessary, it must be coordinated with the locally responsible authority (e.g. city administration or district office). Possible assignments are given below:
Solid salts and solutions containing heavy metals (hazardous waste (special waste) from inorganic-chemical processes): 060313.
Packaging with residual contents of the substance / product is hazardous waste (special waste), waste code 150110.
Absorbent and filter materials, wiping cloths and protective clothing with hazardous impurities are hazardous waste (special waste), waste code 150202.
A verification procedure (proof of disposal and accompanying documents) must be carried out for hazardous waste. Collective disposal is partially excluded.
Completely emptied or cleaned metal or plastic containers can be given for recycling.
Store container tightly closed in a well-ventilated place.
Protect from moisture and water.
Joint storage restrictions (according to storage classes of TRGS 510; the numbers in brackets indicate the respective storage classes):
This substance / product belongs to storage class 13.
Separate storage of explosive substances (1), infectious (6.2) and radioactive substances (7).
For storage together with other explosive substances (4.1A) and ammonium nitrate (5.1C), further regulations must be observed.
Joint storage restrictions do not have to be observed if no more than 400 kg of hazardous substances are stored in total, of which a maximum of 200 kg per storage class.
In general, storage together is prohibited if this would lead to a significant increase in risk, even if the substances are in the same storage class.
This is the case if, for example, they need different extinguishing agents, different temperature conditions, they react with each other to form flammable or toxic gases or to cause a fire.
Requirements of water law for HBV and LAU systems (see also water law checklist):
Systems with up to 0.22 m³ or 0.2 tons are assigned to hazard level A.
The retention volume must be so large that escaping substances can be caught until suitable safety precautions (e.g. sealing the leak, closing off operational parts) take effect.
Depending on the volume of the system for handling substances hazardous to water, there are requirements such as the obligation to notify the lower water authority, specialist company obligations or inspection by experts.
In the case of hazard level A, the obligation to notify does not apply, but the systems must be documented internally.
You can obtain more detailed information on this from your responsible lower water authority, expert organizations, quality and monitoring associations or from specialist companies certified according to WHG.
The storage area must meet the operational requirements and the containers must be tightly closed, protected against the effects of the weather and be material-resistant. For quantities over 1000to, the warehouse must be reported to the authorities.
As a substance / product of WGK 3, the storage of more than 1 t per storage section requires an extinguishing water retention system.
If water-polluting substances / products from different WGK are stored together, the amount must be determined using a conversion rule.
If only incombustible materials are stored in a storage section and neither packaging nor components of the storage can contribute to the spread of a fire, extinguishing water retention systems are not required.
Always wear personal protective equipment when cleaning up leaked / spilled product: In any case, protective goggles and gloves.
Collect spilled product avoiding dust and proceed as described under Disposal.
Product is not flammable; in the event of fire, use fire-fighting measures that are appropriate to the environment.
In the event of fire, dangerous gases / vapors (e.g. sulfur oxides and copper oxide) are released.
Suppress escaping vapors with water spray. Then clean as quickly as possible, as there is a risk of corrosion.
Fight larger fires only with a self-contained breathing apparatus!
Penetration into soil, water and sewage system must be prevented.
