What High Level Cleaning?
High level cleaning refers to the cleaning of high or hard-to-reach areas. High Level Cleaning is applicable in a factory or warehouse roof that is higher than 2 meters from the floor. This type of cleaning often requires specialized access equipment. Equipment such as cherry pickers or scaffolding, and may also involve the use of protective gear to ensure the safety of the workers performing the cleaning.
Examples of High Level Cleaning includes the cleaning of:
- Ceilings, beams and trusses
- Ducting and service lines
- Lighting & fixtures
- Sprinkler systems
- Windows
Accumulated dust and debris can damage equipment, shorten their life span and increase maintenance costs
High Level Cleaning should be done periodically to maintain a high level of cleanliness to the factory or warehouse
What is the Importance of High Level Cleaning?
While routine cleaning focuses on readily accessible surfaces, high-level cleaning delves into the often-overlooked upper regions of your facility. This meticulous process is crucial for several reasons:
- Enhanced Air Quality: Dust and grime buildup in high-level areas can significantly impact air quality, leading to respiratory issues for employees and potentially contaminating products. Regular high-level cleaning removes these airborne hazards, promoting a healthier and safer work environment.
- Improved Lighting: Dust and dirt accumulation can obstruct overhead lighting, reducing visibility and creating safety hazards. High-level cleaning ensures optimal light penetration, fostering a brighter and more productive workspace.
- Reduced Fire Risk: Combustible materials like dust and grease can accumulate in high-level areas, posing a significant fire risk. Regular high-level cleaning mitigates this risk by eliminating potential fuel sources for fires.
- Extended Equipment Lifespan: Dust and debris can build up on machinery and equipment, leading to premature wear and tear. High-level cleaning keeps these vital assets functioning optimally, extending their lifespan and reducing maintenance costs.
- Compliance with Regulations: Depending on your industry, specific regulations may mandate high-level cleaning protocols to ensure worker safety and product hygiene. Regular cleaning demonstrates your commitment to compliance and minimizes the risk of fines or penalties.
Planning and preparation
Before you begin any cleaning work, it is important to properly plan and prepare for the job. This includes identifying the specific areas of the roof that need to be cleaned. You need to assess the potential risks and hazards, and determining the best course of action to take.
One of the first things you should do is conduct a thorough inspection of the roof structure to be cleaned and the factory layout. This will help you to identify any potential hazards or areas of concern that you need to address. You should also look for any obstacles or hazards that may be present on the roof, such as electrical wires or equipment.
You have to determine if the dust you are trying to clean is combustible dust. This will affect the method of cleaning and the selection of tools required to perform this task. Should the dust be combustible you need to ensure you have ATEX Certified High Level Cleaning equipment.
Using the right equipment
When it comes to High Level Cleaning of a factory/warehouse roof, one of the key challenges is working at heights. It is essential to use the right equipment to ensure the safety of your workers and help you to get. Some of the key pieces of equipment you will need include:
Ladders: If you are working from the ground, you will need a ladder to access the roof. Make sure to choose a ladder that is sturdy and properly rated for the job.
Scaffolding: If you are unable to reach certain areas of the roof from the ground, you may need to use scaffolding to provide a stable platform for your workers.
Man cage: A man cage is designed to work with a Fork Lift Truck (FLT). Ensure that the cage is certified and all locks are in place. While the man cage is elevated the FLT MUST be idling at all times, as this machine is designed to lift a load to a set height and lowered to the ground. The hydraulics system does not have a check valve built in to hold a load at a specific height for extended periods. If switched off, this will drift and lower the man cage unexpectedly and cause serious injury to employees.
Cherry Pickers: A cherry picker is often required to clean areas that cannot be accessed by ladders and scaffolding. Ensure that the operator is adequately trained and certified to operate this Elevated Working Platform (EWP)
No matter which method is used, it is important to always use proper safety equipment, such as hard hats, gloves, and protective eyewear. In addition, it is important to follow all safety guidelines and procedures when working on a factory roof structure, including wearing a harness or other fall protection if necessary.

High Level Cleaning is not a daily task, in most facilities this is done once a year or in some cases less frequent. Employees conducting this cleaning operation are often not fluent with this operation there fore thorough training must be conducted.
You must ensure a detailed risk assessment and Safe Working Procedure is conducted. In addition to using the right equipment, it is also important to follow proper safety procedures when working from the ground. This may include:
- Setting up proper barricades or warning signs to alert other workers and pedestrians of the cleaning activity.
- wearing the appropriate personal protective equipment, such as high visibility clothing or reflective vests.
- Having a fall protection plan
- Ensuring a recovery plan is in place should an employe be suspended fall and is suspended by their harness.
- Identifying the nature of the dust you are trying to clean
- Ensuring that equipment being used has a safety check list and is inspected by a trained and certified person
- Sprinkler systems pose an extremely high risk of damage to property if activated. Ensure that personal are aware of this risk and not to break the glass of the sprinkler system.
Disposal Of Dust
Proper disposal of waste materials is important for both environmental and safety reasons. It is important to ensure that all waste materials are properly bagged and disposed of in accordance with local regulations and guidelines, to avoid any potential hazards or environmental impacts.
In the case of combustible dusts, a disposal certificate has to be obtained as companies that have combustible materials are legally responsible for all dusts from cradle to grave.
