However, peel back the comfy seat and leather-clad armrest and most cabs have all kinds of holes for wiring looms and external fittings, meaning they struggle to hold a positive pressure to keep out airborne pollutants without some serious modifications.
This regulation stipulates that dusts, aerosols and gaseous contaminants that arise during the use of toxic substances and liquid fertilisers are not permitted to enter the vehicle cabins. Composting loaders are fitted with Cat 4 filtration systems to protect against bioaerosols, while in construction, excavators can be fitted with specialist systems designed to keep the operator safe from hazards such as mercury contamination.
We asked manufacturers what category they currently build to and for comment on the laws and future plans to build tighter cabs.
This is by no means an exhaustive list of makers but represents a large proportion of the machinery sector. The one exception is the 5G series speciality cabs, used on orchard tractors.
John Deere does not currently claim to provide protection from hazardous substances under this regulation, although the company would always plan to introduce cabs offering higher certification levels where either legislation demands it, or it believes customers would benefit. Cabs with cat 4 certification are costlier for the owner to buy and maintain, and John Deere would not wish to force customers to buy such systems if they are not legally required or provide no additional benefit for the specific user.
Claas highlighted that all its cabs leave the factory at Cat 2 level and all tractors have the option of a Cat 3 upgrade. Claas says that upgrades to Cat 3 are available at factory or retrofit, so the option is there for the user to protect themselves if they wish. All Case-IH tractors leave the factory with Cat 2 filtration and only the Quantum orchard range can be upgraded to Cat 4. On Profi and ProfiPlus there is the option to overpressure the cab to keep dust out, which is needed for Cat 3 and four.
Fendt is working on further protection methods for the future. Cat 4 cabs must be equipped with an aerosol filter with a separation efficiency of An additional charcoal filter to separate hazardous components of the sprayed pesticide is also required and is the difference between Cat 3 and 4 filtrations.
Since then there have been revisions to this, most recently when it was republished on 31 Januarywhich only enhanced the original document.
Vehicles of categories T wheeled tractors and C tracked tractors providing protection against hazardous substances shall be fitted with a cab of level 2, 3 or 4 according to the definition and complying with the requirements set out in the standard EN To find out what it takes to upgrade a factory standard Cat 1 cab to Cat 4, we went to see a filtration system upgrade being carried out by Dumfries-based firm Odour and Dust Solutions ODS.
The three John Deere 6M tractors in question belonged to the Forestry Commission and were being used for a variety of jobs, including spraying and inoculant application. After realising the cabs were only rated to Cat 1, the organisation decided to appoint ODS to improve the level of filtration. To get the machines up to spec, ODS decided to fit a system designed and built in the Netherlands.
Freshfilter has been making these units for more than 25 years and it promises to get almost any enclosed cabin to surpass the Cat 4 standard. The process involves sealing up as many of the air gaps in the cab as possible and blocking off the standard air intakes, before fitting a high-spec air purification unit on the cab roof. Not only does this offer a far higher level of filtration than standard, but it also creates a small pressure difference in the cabin.
This means that if there are any gaps remaining, clean air will be forced out through them, rather than dirty air being able to flow in. The pressure created by the unit is a minimum of pascals Pa but typically Pa and as soon as the ignition is turned on, this starts working.
If a gap opens up somewhere in the cab, the system will automatically up the blower pressure to compensate, and if the gap gets too large for example, a window or door is openedan alarm will sound. To get the required level of filtration for fine mists created when spraying, the firm uses a large volume activated and impregnated carbon filter. Apparently, this needs to be at least 10kg to give enough surface area for complete removal of vapours.
Standard cab carbon filters are far lower than this. This monitors and regulates cabin pressure, shows which filters are installed and records the hours clocked up.
Most cabs can be fitted with the system, but generally the older they are, the more work is required to seal up the gaps. The firm also offers an automatic renewal service with email reminders to get the filters replaced on time.
Both are Cat 1 rated though. The first task was to remove the cab roof and set about sealing all obvious gaps with a combination of foam rubber tapes and plenty of silicon sealant. Next, the standard air filters at the rear of the cabin were sealed and a hole was drilled at the top of the B-pillar.Easy-to-read, question-and-answer fact sheets covering a wide range of workplace health and safety topics, from hazards to diseases to ergonomics to workplace promotion.
Download the free OSH Answers app. Search all fact sheets:. Workers should use respirators for protection from contaminants in the air only if other hazard control methods are not practical or possible under the circumstances. Respirators should not be the first choice for respiratory protection in workplaces. They should only be used:. Respiratory hazards can include airborne contaminants such as biological contaminants, dusts, mists, fumes, and gases, or oxygen-deficient atmospheres. Note that more than one respiratory hazard can be present at the same time.
A hazard control program consists of all steps necessary to protect workers from exposure to a substance or system, the training and the procedures required to monitor worker exposure and their health to hazards such as chemicals, materials or substance, or other types of hazards such as noise and vibration.
A written workplace hazard control program should outline which methods are being used to control the exposure and how these controls will be monitored for effectiveness.
After elimination and substitution, well designed and maintained engineering controls are the preferred methods of controlling worker exposure to hazardous contaminants in the air.
These control methods include:. Administrative controls may be used in addition to engineering controls. Administrative controls limit workers' exposures by scheduling reduced work times in contaminant areas or by implementing other such work rules.
These control measures have many limitations because the hazard is not removed. Administrative controls are not generally favoured because they can be difficult to implement, maintain and are not reliable.
Some types of atmospheres contain concentrations of hazardous substances that places the worker in immediate danger because these concentrations would impair the ability to leave the work area self rescue or potentially cause irreversible health effects, including serious injury or death in a matter of minutes. Employers should have a written respirator program that describes the proper procedures for selecting and operating respiratory protective equipment.
The correct use of a respirator is just as important as selecting the proper respirator. The respirator program must also address how to find out what hazards are present, how much protection that the workers will need, and describe how to wear and look after the respirator.
Without a complete respiratory protection program, workers will not receive the best protection from a respirator even if it is the correct choice for a specific job. A respiratory protection program includes several components such as:. A qualified health care professional should examine the medical and psychological fitness of workers. This evaluation should be done before they are assigned to work in areas where respirators may be required. The workers must be physically fit to carry out the work while wearing respiratory equipment.
They must also be psychologically comfortable e. Workers with beards, long sideburns, or even a two-day stubble may not wear respirators because the hair breaks the seal between the skin and the respirator mask. Wearing eyeglasses would also break the respirator seal. This break means that the respirator mask will "leak" and will not provide the needed respiratory protection.
Also, if a worker has facial scars or an acne problem, the facial skin may not be able to form a good seal with a respirator mask.

Medical browser?A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres, including fumesvapoursgases and particulate matter such as dusts and airborne microorganisms. There are two main categories: the air-purifying respiratorin which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respiratorin which an alternate supply of breathable air is delivered.
FAQs - Chemical Safety
Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants. Air-purifying respirators range from relatively inexpensive single-use, disposable face masks sometimes referred to as a dust mask to more robust reusable models with replaceable cartridges often called a gas mask. All respirators have some type of facepiece held to the wearer's head with straps, a cloth harness, or some other method.
Facepieces come in many different styles and sizes, to accommodate all types of face shapes. The differences in respirator design impact the respirator assigned protection factorsi. There are three categories of particulate respirators: particulate-filtering facepiece respirators are discarded when they become unsuitable for further use due to considerations of hygiene, excessive resistance, or physical damage; elastomeric respirators are reusable because the facepiece is cleaned and reused, but the filter cartridges are discarded and replaced when they become unsuitable for further use; and powered air-purifying respirators have a battery-powered blower that moves the airflow through the filters.
3M Cartridges & Filters for Personal Safety
Respirators can have half-face forms that cover the bottom half of the face including the nose and mouth, and full-face forms that cover the entire face.
Half-face respirators should only be worn in environments where the contaminants are not toxic to the eyes or facial area. For example, someone who is spray painting could wear a half-face respirator, but someone who works with chlorine gas would have to wear a full-face respirator. Air-purifying respirators are used against particulates, gases, and vapors that are at atmospheric concentrations less than immediately dangerous to life and health.

Full hood, half- or full-facepiece designs are marketed in many varieties depending on the hazard of concern using an air filter which acts passively on air inhaled by the wearer. Two common examples of this type of respirator are single-use escape hoods and filter masks. The latter are typically simple, light, single-piece, half-face masks and employ the first three mechanical filter mechanisms in the list below to remove particulates from the air stream.
The most common of these is the disposable white N95 variety. It is discarded after single use or some extended period depending on the contaminant.
Filter masks also come in replaceable-cartridge, multiple-use models. Typically one or two cartridges attach securely to a mask which has built into it a corresponding number of valves for inhalation and one for exhalation. The standard covers certification, ISO registration for the manufacturer, associated test methods, labeling, conditioning requirements, independent process and quality control audits, and follow-up inspection programs.
Mechanical filter respirators retain particulate matter such as dust created during woodworking or metal processing, when contaminated air is passed through the filter material. Wool is still used today as a filter, along with plastic, glass, cellulose, and combinations of two or more of these materials. Since the filters cannot be cleaned and reused and have a limited lifespan, cost and disposability are key factors.
Single-use, disposable and replaceable cartridge models exist. Considering only particulates carried on an air stream and a fiber mesh filter, diffusion predominates below the 0. Impaction and interception predominate above 0.These changes have affected all chemical products that you buy as a business and also those that you buy as a consumer.
As an example: white Spirit is a common organic solvent for use in painting and decorating and can be found in most home improvement stores. The point to note here is that the white spirit in the bottle is no more dangerous now than it was before Decembereven though the label has changed.
This point is the same for all chemical products manufactured and supplied by Magnaflux. Example of white spirit with CHIP labelling. Image credit: www. Example of white spirit with GHS labelling.
As GHS is a voluntary agreement rather than a law, it has to be adopted through a suitable national or regional legal mechanism to ensure it becomes legally binding.
This is what the CLP regulations do. However, CLP was introduced gradually and had a fairly lengthy transitional period before it applied in full on 1 June We also supply a small number of pure substances — for example, our activated carbon, used for filtration purposes. There are no issues associated with end users using product that has the old product labels.
However, if you wish to reassess the product based on the CLP changes please feel free to download the latest version of the SDS from our website and use this to build a chemical risk assessment. Magnaflux Safety Data Sheets SDSs and product labels for product that is currently in production are required by law to carry the same information.
