Judaism Tefilling before sun rise.

[RabbiO]

Shalom chaverim, I have a question about tefilin..
I work in construction and I the only time o have available to put on refueling is 2 hours before sun rise.
I start work at 7 and therefore o have to put on tefillin at 5.
What should I do?
Cant do it at work because I'm dirty from working with cement and cutting wood.
Help please.

You have not told us where on the Jewish spectrum you are - Orthodox, Conservative/Masorti, Reconstructionoist, Renewal, Reform/Liberal? 

If you are a member of a congregation I would suggest that your first resource be the congregation's rabbi... unless, of course, the congregation does not have one.
