The cement manufacturing industry has played a fundamental role in global economic development, but its production is a major facilitator to anthropogenic CO2 release and solid waste generation. Nigeria has the largest cement industry in West Africa, with an aggregate capacity of million metric tonnes (MMT) per year. The Ministry for Mines and Steel Development asserts that the nation ...
The HIRA review is the structured multidisciplinary hazard identification, risk assessment, and methodology that provides a detailed review of hazard, risk, and control of the construction activities. The review is facilitated by the relevant construction personnel in the brainstorming session. CLICK HERE FOR SAFETY OFFICER INTERVIEW QUESTIONS.
1. Introduction. Although the cement industry globally is one of the most important parts of the economic sector, cement production is an extremely CO 2 emission process. Several investigations have been conducted to reduce cement production issues (Chipakwe et al. Citation 2020).They were focused mainly on cement chemistry, and few studies have been conducted on process control and equipment ...
Health risk assessment of TSP exposure through the inhalation route was performed among communities in residential areas from <50 m 5 000 m near the private cement plant. Five locations were chosen according to residential location and wind direction. ... Thermodynamic analysis of raw mill in cement industry using Aspen Plus Simulator ...
Documentation of the hazard assessment is required through a written certification that includes the following information: Identification of the workplace evaluated; Name of the person conducting the assessment; Date of the assessment; and Identification of the document certifying completion of the hazard assessment. Selecting PPE
The oil and gas industry is looking for ways to accurately identify and prioritize the failure modes (FMs) of the equipment. Failure mode and effect analysis (FMEA) is the most important tool used ...

In most cases, the information was drawn from peer reviewed journals and previous Agency data collection efforts in support of regulatory efforts. Much of these data sources were made available for comment to both the public and a panel of independent peer reviewers through the 2010 Human and Ecological Risk Assessment of Coal Combustion Wastes ...
The EPA inhalation risk assessment model and Monte Carlo simulation were utilized to assess the health risks. ... reaching a maximum of and times the OEL, respectively, in the cement mill. Individual metals' cancer risk exceeded the 1E4 threshold in ascending order of Cd < As < Cr. The mean cancer risk of Cr ranged from 835E4 (in raw ...
Cement plant exposure can have a negative influence on the health of both employees and the general public. Gaseous matter and particulate matter are unrestrained into the surroundings during cement making and carriage (Raffetti et al. 2019).NOx, SOx, CO 2, CO, H 2 S, volatile organic carbons, dioxin, furans, and particulate matter are common emissions from cement manufacturing into the air.
The aim of this study is to estimate the risk involved in the cement production process in industries of Pakistan. This research is basically consisting of two main portions. First portion is related to qualitative analysis, such as HAZOP.
The environmental impact assessment (EIA) is an effective tool to manage environmental issues through a generic and regular process, which includes identification and systematic risk assessment of the impacts of a given project or a program on physical, biological, cultural and culturaleconomic aspects of the environment and environmental ...

Methods: A crosssectional study was conducted among cement brick unit workers over two months. A semistructured questionnaire was used to capture sociodemographic details. Multiple observations on the field and the World Health Organization semiquantitative risk assessment matrix were used to obtain risk scores of the occupational hazards.
Additionally, the Portland cement mill technological process (its component parts), as well as the solutions regarding the reduction of the air emissions level, following the emission limit values (VLE), established in the integrated environmental authorization (AIM) from a cement factory in Romania, were analyzed.
The phenomenon was precisely the opposite of the level of 2019. However, we can note that the months of 2019 with a slightly higher level of dust concentration in the stack of the cement mill were August, with mg/Nm 3, October, with mg/Nm 3, and November, with mg/Nm 3.
This paper investigates the process of designing concrete mixtures based on a riskoriented approach. For the risk identification and assessment on the stage of heavy concrete mix composition design, an expert method (Failure mode and effects analysis, FMEA) has been used. Based on the results of an expert survey and an analysis of regulatory ...
EIA stands for Environmental Impact Assessment. UNEP (United Nations Environment Programme) defines Environmental Impact Assessment (EIA) as a tool used to identify the environmental, social and economic impacts of a project prior to decisionmaking. Today we are going to look at one of the most important processes of EIA for the cement industry.
Soil pollution is defined as the buildup in soils of persistent toxic compounds, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health [ 1 ]. Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface.
