If I were you,

If it's really my responsibility/duty, I would send out an email (and cc'ed to boss) to all relevant people in the lab, politely telling them the official/proper formality/procedure of getting certain things done, e.g. to do A, step 1, come to me to keep a record of using material this much; step 2, ...

If not too troublesome, create a webpage and maintain an up-to-date record for everyone to browse; sending out updating email to everyone periodically (e.g. biweekly or monthly) so that everyone will have the impression that you are the person in charge of those stuff.

Keep good relationship with your colleagues/coworkers so that they will respect you more. Then they will skip you less and less.

If it works, don't forget to update you boss, so that he knows you are doing well in this.

Just my 2 cents.
