It's worth noting that a later part of this plan may include gating projects covered under this proposal to members.

The mindset here is that instead of being absolutely prescriptive regarding the types of controls that should be in place we leave that open. This allows us the flexibility to be prescriptive when required and more relaxed when it's appropriate.

From past experience with "maker" groups. do we want to restrict "Drug paraphernalia" as well as drugs? Eg. bongs, nitrous oxide inhalers, pipes. Not technically illegal, but the optics aren't great.

@John "Cheshire" Parker Good point, lets amend it to drugs and drug paraphernalia.

Chemicals: This probably is included in "Substances with the ability to cause harm" however I would suggest specifically including:

• Concentrated acids, bases, and oxidizing agents. This includes but is not limited to: sodium hydroxide, concentrated hydrochloric and sulfuric acid, potassium permanganate, chlorine gas.

• Toxic substances, including heavy metals such as mercury

Some of these have legitimate uses, but you'd really want approval first, and some just shouldn't be done in this setting.

Also please include somewhere:

• Cutting or machining processes likely to form fine dusts, such as cutting or grinding silica or asbestos products.

Really machining silica products is a very bad idea, and OFC asbestos is right out.

Changes:

> Add `material containing asbestos` to the prohibited list

> Rename `Chemical` to `Chemical/Material`

> Add `Concentrated acids, bases, and oxidizing agents. This includes but is not limited to: sodium hydroxide, concentrated hydrochloric and sulfuric acid, potassium permanganate, chlorine gas.` as a subset of `substances withthe ability to cause harm`

> Add `Toxic substances, including heavy metals such as mercury` as a subset of `substances with the ability to cause harm`

I've left off the cutting/machining processes as that is covered under our tool usage guidelines rather than the project itself.

Looking at the temperature section:
- For solids, could activities like ironing (e.g. heat transfer vinyl), or cooking break the 200°C limit? Raising it to 250°C might avoid some potential quibbles.
- 100°C for liquids sounds good, this allows for boiling water.
- The lower limits also seem good. Is there some thinking behind the values of -20°C and -50°C?

For the lower limits its largely just personal experience where things start to stick.

Using a commercially produced iron wouldnt be within the scope of this policy as its a tool and not a project. If you're creating your own iron that hits 200C the intention is that it would be reviewed.

I think clarifying the difference between dangerous project and safe use of tools is probably a good idea. I.e reflow oven gets hot - building your own reflow oven is a nope, but using our reflow oven to reflow a pcb - yes

Added note to top of policy

> This policy only covers projects you work on in our workshop. Tool use is covered under our Training policy

Also adjusted battery welding line to remove the mention of a specific tool.

A specific mention of how to safely use and or store lipo batteries may be useful as well.

Added lipo batteries to Electrical. This policy specifically does not provide safety recommendations so this should be enough to trigger a conversation with the committee.

Proposed changes integrated: https://wiki.artifactory.org.au/en/testing/drafts/dangerous_projects

The new Dangerous Projects policy is now live on the wiki.

We have an outstanding action item from our 2025-02-15 meeting to add a record keeping requirement.

I propose to add the following text:

Record keeping

Approved dangerous projects must be recorded in a place that is visible to all committee members and delegated approvers (e.g. a Slack channel.)

The record must include -

• What the dangerous project is, and who is doing it.

• Who has approved the dangerous project.

• Details of relevant risk assessments.

• Details of agreed risk control measures.
