Safety

DYNACEM contains mainly quicklime and cement (common constituents of building plasters and mortars). Similarly to lime or cement, DYNACEM is classified as an irritant. Explosives possession, handling, storage and transportation safety measures are not required. Using the product without complying to the recommendations within this Data Sheet and the Material Safety Data Sheet, or in a different application, than a recommended one can be dangerous for the user. Silent demolition agent DYNACEM is safe for the environment.

Hygienic Certificate HK/B/0392/01/2016 issued by National Institute of Hygiene, Warsaw, Poland.

Main hazards:

• in case of non-compliance with instructions for use, the product may suddenly heat up once poured into the hole, release smoke or dry up quickly, which indicates it is on the verge of boiling and the water vapour contained inside may rapidly blow the hole contents out into the air, resulting in body damage, protective goggles damage and vision loss, should one look down a filled hole. This may happen when: DYNACEM type (STANDARD/SUMMER), hole diameter, temperature of mixing water and DYNACEM are not tailored to the temperature of the demolished element and/or the mixture is poured into holes still hot after drilling and/or the mixture starts reacting and heating up in the mixer before being poured into holes, and/or the sun shines on the filled holes,
• in case of non-compliance with instructions for use, the product may start reacting when mixed with water, releasing heat, boiling and splashing hot liquid outside of the mixing vessel, which may lead to burns or serious eye damage. This may happen when the stirrer and the vessel are unclean and the remains of the previous batch enter the fresh one, mixing time is too long, or the items were stored in a warm place,
• product transport, or stirring may generate dust which forms a highly alkaline environment when in contact with sweat, or tears. This may result in skin and mucous membrane irritation, burns and serious eye damage.

How to mitigate hazards:

• download the up-to date version of the Material Safety Data Sheet and the Data Sheet from www.dynacem.pl/uk,
• assign a capable and responsible person to handle the product. Ensure that they have read the MSDS and the Data Sheet, remember and understand the rules of product handling, safety and personal protection,
• when planning the work, keep in mind that destroying the first element/fragment, may affect the stability of the structure and cause it to collapse,
• ensure there is a high quantity of clean water available on site to wash the skin, or eyes in the event of exposure,
• do not use contact lenses, do use skin protection cream, wash hands before breaks and after work,
• use personal protective equipment marked CE: goggles, chemically resistant gloves, half face dust masks (full face masks for long term work in dusted areas, or in confined spaces), hard hats, and coveralls (long sleeves and legs),
• do not induce dusting,
• observe the product when mixed with water. If the grout starts to heat up, or smoke, stop stirring immediately and spread it on the ground,
• never pour the mixed grout into closed receptacles, receptacles with a tapering rim (e.g. bottles) and into holes within wooden elements,
• in the summer, aim to carry out the work away from direct sunlight – in the afternoon or in the morning, do not store the materials in the sun, try to use cool water, vessel and agitator. Use a bright cover to shield filled holes from direct sunlight, or rain,
• ensure that no one approaches the holes or looks towards them for at least 12 hours from filling,
• ensure that no one, under any circumstances looks directly into the filled holes,
• store in a dry place.

First aid:

• eye contact: rinse eye in running water for several minutes and consult a doctor immediately,
• skin contact: wash the irritated/burnt area with water and soap and rinse thoroughly,
• inhalation: escort the affected personnel from the dusted area (adhere to PPE guidelines and avoid personal injury) and seek medical help,
• ingestion: rinse mouth with water and drink cold, clean water in small portions. Do not induce vomiting and seek medical help immediately.
