Gigiena I Sanitariia
|July 10, 2015
Summary
This study assessed chemical risks in new refractory manufacturing, identifying magnesium oxide, resin vapors, and dust as key hazards. Mitigation strategies were developed to improve worker safety and reduce respiratory illnesses.
Area of Science:
- Occupational Health
- Industrial Hygiene
- Chemical Risk Assessment
Context:
- New refractory manufacturing presents unique occupational chemical risks.
- Ensuring chemical safety in Russian industries is a priority.
- Periclase-carbon refractories with organic binders are a novel product.
Purpose:
- To assess occupational chemical risks in new refractory production.
- To identify main health hazards for workers.
- To develop risk mitigation measures.
Summary:
- Chemical risk assessment involved hygiene studies, worker morbidity data, and animal testing (intratracheal introduction).
- Key risks include magnesium oxide, phenol-formaldehyde resin volatiles, silicon dust, CO, SO2, NOx, benzo(a)pyrene, and pitch cokes.
- Workers showed elevated upper respiratory disease rates; dust exhibited general toxic and mild fibrogenic effects in animals.
Impact:
- Developed targeted risk mitigation strategies for workplace safety.
- Provides data for improving occupational health in the refractory industry.
- Contributes to chemical safety protocols in new industrial settings.

Deleterious Substances in Aggregate
769
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.

Portland Cement
1.4K
Portland cement is the essential binding ingredient in concrete, made from finely ground materials including lime, iron, silica, and alumina. Lime is derived primarily from limestone, marble, marl, seashells, and clays, which also supply iron and alumina, while silica is sourced from sand, chalk, and bauxite. Contemporary manufacturing of Portland cement is a significant source of carbon dioxide emissions, prompting research into reducing its content in concrete through alternative...

Retarders
321
Retarders are chemical admixtures designed to extend the setting time, which is especially useful when there is a delay in sequential concrete pours to prevent cold joints and to achieve a cohesive structure. Retarders, when used in appropriate amounts, can also enhance the architectural appearance of exposed aggregate finishes.
The function of retarders is to delay the setting of concrete, and this effect can be measured using a penetration test. The retardation process involves adding...

Toxic Reactions: Overview
3.9K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Polymer Classification: Architecture
4.1K
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

Mortar
764
Mortar, a mixture of Portland cement, hydrated lime, sand, and water, is a crucial binding material in construction. Its primary function is to join masonry units together, filling gaps and ensuring a uniform distribution of weight across the structure. This helps in preventing potential weaknesses. Mortar also serves as a protective barrier against environmental elements such as water and wind, thereby safeguarding the interior of the structure. It also compensates for surface irregularities...
