Optimizaci贸n de almacenes: Equilibrio entre el rendimiento de los equipos y la seguridad de los trabajadores mediante la medici贸n de las emisiones y la supervisi贸n de la calidad del aire

balance

Successful warehouse functionality is dependent on both maximizing equipment performance and providing a safe and healthy environment for workers that encourages productivity. However, these two factors are often at odds with each other as warehouse equipment such as forklifts, burnishers and delivery trucks emit toxic gases that can have the potential to create poor indoor air quality which affects worker respiratory health and overall productivity. Warehouse managers and supervisors should optimize the balance between equipment performance and personnel safety and comfort to achieve maximum production.

Warehouse Equipment Emissions and Sources

Three toxic gases that may be present within a warehouse are carbon monoxide (CO), nitrogen oxides (NO/NO2/NOx) and volatile organic compounds (VOCs). Elevated levels of any one of these gases may result in immediate health issues including shortness of breath, headaches or nausea and long-term effects such as respiratory distress, cancer and, in extreme cases, death. These gases are generated from a variety of causes necessary for successful daily warehouse function, and are exacerbated by poor ventilation, particularly in winter months when warehouses are normally sealed off from cold weather.

Strategies for Optimizing Equipment Performance and
Worker Safety/Productivity

Warehouse managers and supervisors have a variety of strategies for optimizing performance of equipment and worker safety and productivity:

1. Monitoring Warehouse Equipment Emissions and Efficiency
Periodic monitoring of emissions from gas & diesel powered forklifts and other equipment that emit toxic gases provides information on each machine鈥檚 contribution to air quality, but also on the vehicle鈥檚 efficiency. High emissions from Forklifts and other sources may indicate an equipment malfunction requiring maintenance in order to:
鈥 Optimize equipment efficiency & maximize fuel savings
鈥 Identify and quantify the sources affecting the safety & comfort of the work environment.

Emission gas levels should be measured near the tailpipe using a portable gas analyzer and adjustments should be made to the throttle and fuel delivery system in order to ensure a clean burn.

2. Indoor Air Quality Monitoring
Even a small amount of exhaust gas can result in a significant build up of CO and NOx in the air. Periodic measurements of air quality at a wide variety of locations of a warehouse provide an understanding of potential safety problems that may be occurring for on the floor personnel. Elevated levels of CO, NOx or other toxic gases will have negative effects on worker productivity and safety.

3. Determining the objectives associated with emissions and performance required for Forklifts, Burnishers, and other equipment in the premises Warehouse managers should assess the current conditions and establish targets for the pollutants emitted by the different sources and the acceptable indoor air quality levels of toxic gases such as CO, CO2, NOx, and VOCs in order to create and implement air movement/replacement strategies when these levels are exceeded.

4. Implementing a Long-Term Air Quality Optimization Strategy (Air Quality/Movement/Replacement) to Avoid Toxic Gas Build Up Warehouse supervisors should consider designing and implementing a long-term air movement and replacement strategy that aims to:
鈥 Maintain the air quality standards required to safely run the warehouse
鈥 Measure and evaluate the performance of all of the contributing factors to warehouse air quality
