RTOS: Posting semaphore when HWI disabled

Tool/software: TI-RTOS

Is it safe to pend/post semaphore when hwi is disabled. For example,  I have a concurrent access queue, and I disable the hwi interrupts when I am insterting or removing an item from  the queue. However,

I also need to post or pend a posix semaphore inside this block(holds item count). Is is safe?

Thanks.
