In January 2025, a Diesel Engine Exhaust Emissions (DEEE) Assessment was carried out at a Leeds Station to check air quality for staff working around diesel trains. The assessment focused on platform and gate operatives who are often close to idling trains, with the goal of making sure that diesel fumes aren’t posing a health risk.
The results were reassuring overall; no exposure levels went over workplace safety limits. However, some readings for elemental and total carbon were flagged as significant, especially for dispatch staff working on the platforms. These levels don’t require immediate action, but they do suggest it’s worth tightening up control measures.
To reduce risk, the report suggested limiting unnecessary engine idling, improving train maintenance and exploring ways to boost ventilation in areas where exposure is higher. It also recommended regular air quality checks and health monitoring to keep things on track.
By putting these measures in place, the station can continue operating efficiently while also making sure the team is working in clean, safe air every day.
Sysco Environmental Ltd recently completed a project in Ferrybridge, where we monitored fumes, including diesel exhaust fumes, from various generators during the decommissioning of a large power plant. This large-scale operation involved numerous vehicles and activities, generating a variety of hazardous fumes. Our team conducted extensive air quality assessments to measure the concentrations of these fumes and identify potential risks to the workers involved.
