Health and Safety
Mexboro specialises in the manufacturing of architectural cast stone dressings and bespoke and precast structural units.
Our concrete is produced from regular constituents. When presented in their normal form, they are unlikely to give rise to any significant risk to health.
Constituents used are:
- Natural and Artificial Aggregates
- Cementing Agents
- Additional Binders
- Non-Toxic Iron Oxide Pigments
- Steel Reinforcement
- Steel Fixings
Physical and Chemical Characteristics
Our precast concrete products are manufactured by the compaction and/or vibration of a hydrated mix of constituent materials, which subsequently undergo a curing process.
Precast concrete of this nature can be considered to be inert, and therefore presents no major chemical hazard.
- Handling of precast concrete products may cause abrasive damage to the hands
- Manual handling of precast concrete should only take place where the weight of the unit(s) permits. Otherwise, injury may occur
- Steel reinforcement, which may be integrated into some precast units, may constitute a fire hazard from the resultant sparks if the units are to be cut
- Cutting, drilling, grinding, or similar treatment of the products will give rise to respirable dust. Such dust, if inhaled in excessive quantities over extended periods, can constitute a long-term health hazard
- Cutting, unless adequately controlled, can project particles at high velocity, with consequent risk of impact damage. Wet cutting is recommended
- Excessive handling may cause dermatitis or drying of unprotected skin
Cleaning and Maintenance
Periodic cleaning may be carried out by washing with water and mild detergents using soft brushes. For more thorough cleaning, refer to specialist concrete cleaning agencies.
Aggressive cleaning with high-pressure washers and/or diluted acids may leave units with a coarser texture, which will change the apparent colour.
- During cutting or similar surface treatment, inhalation of dust should be avoided and eyes protected.
- When working with heavy, dense, cementitious building products, personal protective clothing such as gloves and protective footwear should be worn.
- Care should be taken when handling heavy components, and mechanical lifting equipment should be used in accordance with the Manual Handling Regulations.
- Care is required when cutting and disposing of any steel bands to avoid injury.
- Gloves and goggles should be worn.
Transportation and Storage
It is not necessary to adhere to hazardous substance conveyance regulations when transporting precast concrete or cast stone. Vehicle labelling is not required.
Particular care should be taken in the handling and stacking of units or packs of units. Taking into account the weight and stability of the packs, method of handling, and condition of the ground.
Hardened concrete is inert, but should be disposed of in accordance with local regulations. In some cases, reinforced concrete will need to be separated from unreinforced concrete prior to disposal.
Products may be delivered in packaging made of polythene covers, steel strapping, and wooden pallets. All types of packaging require careful site disposal after use. In particular, haphazardly burning polythene covers and wooden pallets will release smoke and fumes, which can be inhaled in sufficient quantities to be injurious to health.
