Practical life of organic compound carbon filters

Mark  Member

Most of our finishing jobs go to a dedicated finishing shop, but like it or not I am slowing becoming "the guy" for small lacquer jobs at work. We also have to buy all of our own PPE, so when I spray I use a 3M 3000 series respirator with organic compound carbon filters. Because of the virus, I can't get filters at the local home depot like I normally do. How long do you guys in practice use these filters? Also, if you are not in a full hood, how important is it to protect your eyes? Spraying inside boxes, is when I am really aware that I should be thinking more about how this could effect my eyes. I am spraying in a huge wear-house, with a moderate fan in the door. I would love to hear any PPE pro tips you guys have. I only have so many brain cells, and I need to keep all that are left.

Maybe you can search a spray gun with a different tip to apply inside de boxes , that will create less over spray

Get a full face mask. And get tear away lens shields. The bounce back will ruin your eyes. Advanz makes a goggle with 30 frames of rolling lens which is good option with a basic face mask. Technically the charcoal deteriorates pretty quick if left out. Like 7 days.(I built surfboards back in the 70/80s early 90's and lived in a mask) When not in use put it in a tupperware container.

Totally agree on full face mask with lens shields.

Beyond that,
1. Get the cartridges that have the service life indicator (60921i) Then you don't have to care, it'll tell you how long it lasts.

2. Get resealable mylar bags and put the filters in them. They will last a lot longer.

can you leave the backs off and spray them separate and then install them after everything drys.

Why do you have to buy your own equipment.Should be a company expense.
Rather than going to Home Depot use a safety supply company.they will have better products and be more knowledgeable.
I use a full face supplied air system.
Try northern supply.

Like Muaricio said, changing the tools you're using could dramatically lessen the amount of overspray you're exposed to..if you're not using a AAA setup, get one, it's amazing how little overspray they produce especially when spraying inside boxes.
Another option is to change the product your using. Going from solvent lacquer to a waterborne product could cut the amount of VOCs your exposed to by up to 90% (not to mention the personal safety benefits of going from a flammable product to a nonflammable one [a change that will save insurance $ too]).

I guess the company you work for has never had a visit from OSHA, the local fire marshall, or insurance inspector? Hard to count all the issues in those pictures.

I've always been told 8 hours of use and they are done.

Switch to the 3M 6000 series. It's so much more comfortable. Get the larger size because it's a tight fit as a mask sits on the bridge of your nose. If you're sporting a beard, either shave it off or you will need a fresh air supply respirator. I think federal guidelines are such that your employer is required to provide you with the proper PPE, but it's their choice what brands & models.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk. WOODWEB reserves the right to delete any messages it deems inappropriate. (return to top)
